The purpose of this work is to discuss the tulip contact behavior during mechanical and electrical simulations in a Finite Element Method (FEM) environment using ANSYS and COMSOL software. During the simulations, the full contact movement was analyzed. During the contact movement, the individual behavior of the contact components was taken into consideration. The motion simulation was carried out at different velocities and forces acting on the contact. The obtained results were compared to each other and discussed. Relatively, the angles of the contact surfaces to each other were also changed, which meant that we could conduct a more in-depth analysis. The other approach of simulation research was a field analysis of physical phenomena occurring in the tulip contact. This analysis was performed in COMSOL Multiphysics. Parametric analysis allowed an observation of the electric field in the tulip contact at different contact distances with respect to each other. This work is importan...

Fused Depoition Modeling is a type of Additive Manufacturing technology, which has capability to construct final product by mean of adding layer by layer pattern automatically from data generated by Computer Aided Design (CAD) model. This research work focused over the study of effect of process parameters such as infill percentage, Shell wall thickness and extruion temperature with specimen material used as ABS. This Research work includes optimization of the process parameter using statistical method Response Surface Methodology(RSM(and validating parameter's significance using ANOVA. To overcome some of the drawbacks such as time consumption of printing, machine speed, quality of surface, required properties namely strength, thermal and mechanical properties optimization of process parameter is importand. It is also equally important to find out correlation between process parameters and response outcomes required. Hence, it was proposed to carry experimental investigation of FDM process parameters on polymeric materials because polymeric materials are easy to print as well as economical with wide range of application. FDM process is simple process as compared to other processes so on that basis FDM is chosen. In order to carry work methodology, sample specimens prepared according to ASTM standard for tensile test. Results carried out according to performing test to investigate the relationship between parameters and concomitant effect on strength. Major reason for weak strength of FDM processed parts owes to distortion within the layer or between the layers while building the parts due to temperature gradient. The utility of RP parts suggests that it is dependent on various loading conditions and hence needs to be optimized to gain effective practical implications and optimistic improvisation according to requirements.

The laminated tapered beams are increasingly being used in engineering applications, such as turbine blades, helicopter blades, aero-foils, yokes, robot arms and satellite antennas where in the stiffness of the structure needs to be varied along the length of the beam. Such tapered laminated structures, which are formed by dropping off some of the plies at discrete positions over the laminate, have received much attention from researchers because of their structural tailoring capabilities, damage tolerance, and their potential for creating significant weight savings in engineering applications. The inherent weakness of this construction is the presence of material and geometric discontinuities at ply drop region that induce premature inter-laminar failure at interfaces between dropped and continuous plies. In this present work, the effect of these ply drops on the stress distribution on a composite structure is considered. In this work ,three composite models (with symmetry & unsymmetrical orientation angles)aredeveloped with and without ply drop off. The ply-drop off models is considered as external taper type and mid plane taper type. The maximum stress in all the three models is to be compared and the effect of the ply-drop on the stress distribution is to be studied. The effect of fibre orientation and the strength of composites are studied by using ANSYS software to estimate its strength when pressure load is applied.

1. Abstract This paper explores various level measurement techniques used in industries for level measurement in the tanks. Level measurement technique helps to predict the amount of liquid available in the tank. Level measurement may be of continuous or point values, continuous level measurement gives exact amount of liquid in the tank whereas the point value gives only the level of liquid about a specific sensing point. There are several methods of level measurement available in the present industry. All these measurement techniques employ various engineering principles. RF capacitance, Conductance (conductivity), Hydrostatic head/tank gauging, Radar, Ultrasonic are some of the methods used [1]. This paper also makes a comparative study of various level measurement methods. 2. Introduction 2.1 Level Measurement Liquid level measurement techniques are widely used in industries and domestic applications. The measured fluid need not be in a container it can also be natural form like river, lakes etc. This is techniques are widely used to protect and control the usage of natural resources like water. There two type of level measurement they are a) Direct measurement b) Indirect measurement. Direct methods are very old and beings used from industrial revolution. They are mainly to measure and monitor liquid levels in tanks and other storage containers. The advancement in the electronic and electrical engineering gave way to variety of indirect and comparatively easy level monitoring systems available at present [2]. Direct Methods like dipstick, viewing glass or using floats in the liquid are more commonly used and they are relatively simple. These methods only gives, where the liquid level is or we may have to make level marking according to the volume at various levels. These methods are good as they can give direct vision of the tank level. These methods are not suitable when the tank is far away or Human accessibility is difficult. There comes the importance of the Indirect (Electrical) measurement techniques, they are very convenient and suitable for remote monitoring of liquid levels. 2.2 Importance Level measurement has significant importance in the industrial applications, especially in oil & gas and mining applications to monitor the amount of fluids. Level measurement techniques are even used in powdered material monitoring in industries. Liquid level measuring are used in mobile equipments used for mining applications where fluids are monitored from a point, the operator of the plant or equipment can monitor the amount of various liquids by sitting at his cabin. In this paper mainly explore and compare about a direct method and some of electrical sensing (indirect methods) used.

- Fatigue, FEA with ANSYS

In an IC engine, the most heavily stressed part is connecting rod. Its functionality is connecting crankshaft and piston, which transfer energy from piston to crankshaft and converts linear piston reciprocating motion into crankshaft rotational motion. Under the engine cyclic process, the connecting rod is subjected to tensile and compressive loading. The main forces occurred on the connecting rod are forces due to maximum gas pressure and the inertia of connecting rod plus reciprocating masses. The connecting rod must have maximum stiffness at the minimal weight. This research work is focused on modeling and analysis of connecting rod stress, deformation, fatigue strength, and life prediction for Toyota Hilux diesel engine made by four candidate materials (aluminum alloy 7068T6, aluminum alloy 7050 T765, carbon steel C-40 and forged steel 4340). The connecting rod model was done by CATIA V5R20 and Numerical prediction of the desired parameters has been evaluated by considering the ...

These combination of materials that are now mostly used in the world of civil engineering construction,
especially on the long-span structures such as bridges, is a combination of concrete and steel. In the
combination of these two materials, the use of concrete materials applied to the beams and steel material used
in the form of strands of wire as cable tendons that cross sectional longitudinal beams in such a way that when
tensed will generate a compressive stress in the fiber concrete beams, which is better known as prestress
concrete. This study aims to determine the effect of variations cambering and prestressing force at ultimate
ability prestress beam bridge.
Beam models created with the help of ANSYS Ed. 9.0 program. Prestress beam were modeled along 16
m with concrete strength f􀀂
􀀃 = 41,4 MPa and prestress ultimiate tensile strength f􀀄􀀅=1862 MPa. Loading on the
model of the column is a concentrated load in the middle of the span, with a variation of prestressing force.
Cambering value, which behave as opposed deflection used is in the range of values that permit the beam
deflection and exceed them. The results of finite element analysis with the help of ANSYS program will be
analyzed using polynomial regression to determine the equation of the modeling results.
The higher prestressing force is applied, deflection that occurs will be smaller and will also increase the
capacity of the first crack load and ultimate load. Cambering given on prestress beam will increase the ability
to resist deformation and reaches deflection opponents, but it will decrease the ultimate load capacity. The
most effective value of cambering when viewed from reaching opponents deflection and ultimate load capacity
is 1/320 L.
Keywords: Prestress bridge, cambering, ultimate strength, polynomial regression, finite element.

The development of new aircrafts over the years has been accompanied by advanced technology or introduction of new technologies for improved performance. Over the decades, the aviation industry has spearheaded the development of advanced systems and successfully integrated these technologies in aircrafts. Among these is the air conditioning system which has increased passenger comfort in a range of flying altitudes/ flight regimes. There is a new aircraft in its final stages of production, the Cessna 408 Skycourier, scheduled to take its initial operation flight in 2020. This project endeavours to design an air conditioning system for the aircraft to enhance passenger and crew comfort and also meet FAA CA 25-20 regulations which recommends aircrafts flying above 15,00ft be conditioned and pressurised. The bleed system of air conditioning is the most commonly used system, however, this comes at a compromise of reduced engine efficiency by draining bleed air from its compressor section. Thermacool system is another system adopted in small and light sport aircrafts without having to drain the engine. On the other hand, its demerit is the use of refrigerants in cooling which cause ozone degradation. A bleedless air conditioning system is therefore adopted in this course mitigating on system complexity for easy maintenance. Bleedless air conditioning is employed by the Boeing 787 Dreamliner. However, this system demands large amounts of energy which caused electrical power problems for the B787. The system in this design seeks to use available technology and equipment to device a system with less power and maintenance requirements. A conceptual design is developed which gives a paradigm of the configuration of the system. This is the initial stage of design and involves brainstorming multiple configurations and making a call after several iterations. From this baseline, a preliminary design is developed which comprises of CAD models developed in SolidWorks. This phase is a step further to actualization of the design and involves a comprehension of how the system components will work and performing tests and analyses to access the viability of the design configuration in meeting the system objectives. These comprise of structural and flow simulations carried out in Ansys software.

The manuscript presents advanced coupled analysis: Maxwell 3D, Transient Thermal and Fluent CFD, at the time of a rated current occurring on the main busbars in the low-voltage switchgear. The simulations were procured in order to aid the design process of such enclosures. The analysis presented the rated current flow in the switchgear busbars, which allowed determining their temperature values. The main assumption of the simulation was measurements of temperature rise during rated current conditions. Simulating such conditions is a valuable asset in order to design better solutions for energy distribution gear. The simulation model was a precise repre-sentation of the actual prototype of the switchgear. Simulations results were validated by ex-perimental research. The heat dissipation in busbars and switchgear housing through air con-vection was presented. The temperature distribution for the insulators in the rail bridge made of fireproof material was considered: halogen-free polyester. The results obtained during the sim-ulation allowed for a detailed analysis of switchgear design and proper conclusions in practical and theoretical aspects. That helped in introducing structural changes in the prepared prototype of the switchgear at the design and construction stages. Deep analysis of the simulation results allowed for the development concerning the final prototype of the switchgear, which could be subjected to the full type tests. Additionally, short-circuit current simulations were procured and presented.

The suspension system of every vehicle needs to be adaptive, durable, efficient, and relatively inexpensive . The vehicle must be able to withstand the harsh environment of off-road competition and recreational driving. The vehicle needs to traverse over large rocks, downed logs, mud holes, steep inclines, jumps, and off camber turns. In order to meet the demands of the race course, the suspension kinetics should be analysed and examined carefully. In suspension kinetics vehicle’s loads absorbing capacity, resonant frequency, ride quality and handling performance has been analysed using quarter car and bicycle car model. Ride quality and handling performance of the vehicle can also be optimised by varying damping ratio and frequency ratio through frequency response analysis

The importance of overtaking investigation is to ensure that vehicle can remain stable under turbulent conditions. The
flow distribution occurring on a light vehicle (bike) when it passes over a heavy vehicle (bus) is investigated using three
dimensional (3D) Computational Fluid Dynamics. Previous tests have been researched and compared; it was found that, the
overtaking vehicle causes the other vehicle to experience sideward forces, leading to roll followed by undergoing a yawing
moments as well as reductions in speed caused by changing pressure distributions throughout the vehicles. An aerodynamic
characteristic of a vehicle is a significant interest in reducing accidents due to wind loading and in reducing the fuel
consumption. To avoid accidents we should reduce the wake region of the entire body of each vehicle. For that modulation in
shape the boundary layer condition are changed and the flow separation are also reduced to small.

The connecting rod was manufactured by forging process for enhancing high tensile and compressive load so that it was followed by the machining process and suite the IC engine as a part of the component. The main intern of our proposed work is to manufacture a two set of
composites specimen of A356 alloy with reinforcement of 5 wt.% silicon carbide and 10 wt.% flyash processed through two different techniques like stir casting and stir cum squeeze casting route and obtain better mechanical properties. Further, the same properties were taken for modeling and analysing of the developed connecting rod model. Due
to the commercial demand, the hybrid composite materials take a vigorous role in the analysis part of the connecting rod model. The FEA analysis is done on the connecting rod for a180cc engine by using Ansys 18.1. The static analysis is done by considering four different cases by altering material library property. The output parameter such as total deformation, Von Mises stress, and maximum equivalent elastic
strain are taken in each condition. The analysed results show
that the material property of aluminium alloy A356 reinforced
with 5% SiC and 10% flyash was cast under stir cum squeeze casting condition opt better results when compared with conventional stir casted connecting rod model and also the specimen of A356 alloy with reinforcement of 5 wt.% silicon carbide and 10 wt.% flyash under stir cum squeeze casting will have better material property.A356 reinforced
with 5% SiC and 10% flyash will have better results and
higher material property when compared with previous
similar researchers. So this composites and process were
recommended for manufacturing of connecting rod for
automobile applications.

Floor beam is a structural part of a fuselage which is used as floor space to passengers, cargo and fixed with fuselage skin. Here, the cross beam has taken as I-section and connected with attach bracket methods of joining. The design of aircraft floor beam is conceptual design for the cost and weight reduction, strength improvement and ease of fabrication of fuselage. Increased weight and less stiffness of the existing floor beam made of aluminum is major problem of present floor beam. Hence, CFRP (carbon fiber reinforced plastics) has chosen for the designing of floor beam in the aircraft. After the selection of material and cross section of floor beam, the whole parameters of cross section of floor has studied and designed in UG NX8 software then the model is imported to Ansys 14.5 for the dynamic analysis and life estimation. The expected outcome is to reduce the weight to strength ratio, cost, increase the durability and life cycle of cross beam.

The time for which the vehicle runs is roughly 2 hours and vary depending on the speed at which the vehicle travels. The torque and power of the motor and are selected from the various configurations available in the market and which satisfies our requirements also. The wheels used are hub motor type wheels in which the motor is situated inside the hub of the wheel at the center. These wheels are not generally available in India and need to be imported. These wheels require less torque and power when compared to motor driving the wheel. The input to the wheel is given through an accelerator and is controlled using an electronic controller. Brakes can be applied to any wheel and turning the vehicle can be done by applying brakes on any of the side required depending on the direction of turn to be taken. For the vehicle to stop completely both the brakes need to be applied.

Fibers and bacterial additives in concrete have achieved significant success as a construction material. This paper presents the field of concrete self-repairing by introducing both Bacillus subtilis bacteria and polyethylene fiber as a dual-components. The main research goal is to reveal the principles of concrete self-repairing. At first, the research investigates the fiber-reinforced-concrete behavior, the concrete self-repairing process with the Bacillus subtilis bacteria for forming bacterial-concrete. And then, the study highlights the damage-repairing numerical simulation of fiber-reinforced-bacterial-concrete. The research shows the bacterial-concrete benefits to durability and mechanical properties besides to the polyethylene fiber assistance to enhance post-cracking tensile resistance and the pre-peak elastic modulus of concrete. The novelty of the fiber-reinforced-bacterial-concrete is the matrix combined improvement of both basic material properties and the post-cracking deflection capacity.

In this paper, experimental as well as numerical analysis of Glass Fiber Reinforced Polymer (GFRP) laminated composite has been presented under ballistic impact with varying projectile nose shapes (conical, ogival and spherical) and incidence velocities. The experimental impact tests on GFRP composite plate reinforced with woven glass fiber (0°/90°)s are performed by using pneumatic gun. A three dimensional finite element model is developed in AUTODYN hydro code to validate the experimental results and to study the ballistic perforation characteristic of the target with different parametric variations. The influence of projectile nose shapes, plate thickness and incidence velocity on the variation of residual velocity, ballistic limit, contact force-time histories, energy absorption, damage pattern and damage area in the composite target have been studied. The material characterization of GFRP composite is carried out as required for the progressive damage analysis of composite. The numerical results from the present FE model in terms of residual velocity, absorbed energy, damage pattern and damage area are having close agreement with the results from the experimental impact tests.

The fundamental motivation behind this paper is to enhance the crash worthiness, reduce the weight and improve the cost of the bumper. Designing a heavy vehicle bomber and sequential analysis on how it influences the parameters, for example, shape, thickness and material will help in increment the quality and lessening in weight. This additionally gives a method for utilizing materials that are recyclable and biodegradable which helps in controlling natural contamination. The bumper beam of the heavy vehicle is modelled and analyzed with the steel material and then the design is modified and improvised by using a shape optimization tool in the FEA. In light of the shape enhancement comes about the state of the model is adjusted and replaced with aluminum and composites. shape of the bumper are premeditated for the analysis on an automotive bumper to enhance the properties of the beam particularly to stand against the impact forces of crash, ranging from medium speed to high speed impact collisions. From this work it is recommended that S2 glass epoxy is performing extremely all around contrasted with the current bumper material. The stress is diminished by 45.14% and the deformation is decreased by 55.25%.

Mixed thin-walled structures have been widely applied in automotive technology and arouse a lot of interesting, such as sheet-beam structure and varying cross-section beams. Two of distinct classes of finite element models can be used to support the design and analysis of such structures: detailed models and concept models. This paper presents a method to generate the concept models for the mixed thin-walled structures, such concept models are validated through structural and NVH analyses. Although the discussion is based on specific structure models, the conclusions are generic and applicable to other mixed thin-walled structures of the same nature.

The developed Strut-and-Tie Model (STM) has no unique shape for each load case
of a given structural problem as long as the selected idealized internal load-resisting
truss is in equilibrium with boundary forces, and also stresses in its components
"struts, ties, and nodes" are within acceptable limits. However, the optimal shapes
are the well-designed with best ordinal weight number of conditional factors as the
rebar amount, the load factor, and the structural concrete ductility. The current
study investigates numerically based on FE method stress flow contours and micro
truss techniques many alternatives with different shapes of struts and ties that
transfer the flow of forces from top of the deep beam with opening to both right and
left supports. Then, these alternatives with different concrete characteristics are
analyzed by strut-and-tie computational tools using different code provisions for
verifying its results accuracy with the numerical nonlinear finite element analysis
results for studying the structure performance under applied service loads and over
loading till failure. The chosen alternative produce load factor to reach capacity
greater than 1, therefore the strut-and-tie method always give demand collapse load
lower than the true capacity collapse load. This implies that the solution obtained
from STM usually lies on the safe side with conservative sense for concrete
structures subjected to service loads. That’s why the STM is emerging as an
increasingly popular code-worthy methodology for the design and detailing of
concrete structures D-Regions.

In this paper we are discussing the machining of aluminium has been conducted at normal cutting conditions and the chip formation during machining is analyzed using FEM, the mean coefficient of friction between the tool and the work piece is made constant as it affects the tool design, tool material selection and cutting parameter selection. So it is exceedingly important to have the complete knowledge of the frictional boundary conditions at the tool-chip contact region where the chip formation takes place. Here we are taking the commercial Aluminium and high speed steel materials and we have done our work using two different software Ansys Workbench and LS-DYNA and using two different types of formulations. In Ansys work bench simulation contains Lagrangian formulation but LS-DYNA contains ALE (Arbitrary Lagrangian and Eulerian) formulation and in LS-DYNA we go through considering the work piece as SPH (smooth particle hydro dynamic) element actually used for fluid solid interactive element is adopted .By this two methods we have run the both processes and we compared the both results such as von-mises stress and tresca stress (maximum shear stress), elastic strain and plastic strain etc.

This study investigates stress and deflection of cantilever beam under 3 different load configuration which are load applied at one free, uniformly distributed load and uniformly varying load. All loads are vertically concentrated. The cantilever beam that has been used in this project is of long, slender with uniform rectangular cross section made of linear elastic material properties that are homogeneous and isotropic.
The weight of the beam is assumed to be negligible. It is also assumed that the beam is inextensible and so the strains are also negligible. Considering this assumptions at first using the Bernoulli-Euler’s bending moment curvature relationship, the approximate solutions of the cantilever beam was obtained from the general set of equations. Then assuming a particular set of dimensions, the deflection and stress values of the beam are calculated analytically. Finite element analysis of the beam was done considering various types of elements under different loading conditions in ANSYS 15.0.7 the various numerical results were generated at different nodal points by taking the origin of the Cartesian coordinate system at the fixed end of the beam. The nodal solutions were analyzed and compared.

The analysis and design of hydrodynamic journal bearings has a great attention to the engineers. Emphasis has been given to design those bearings so as to avoid metal-to-metal contact .To design these elements, few important characteristics, like load-carrying capacity, maximum pressure and their location lubricant flow requirement between mating surfaces, etc. are to be predicted accurately. These parameters can be determined if the pressure within the clearance space between contact surfaces is known. To study and find this pressure one has to solve in general the Reynolds’s equation that governs the flow of lubricant inside the clearance space. Moreover the accuracy of the results obtained by FEM is mainly depends on the proper finite element modeling that includes proper selection of the type and size of finite elements and solution algorithm. As computing cost and time increases the size (i.e. the number) of elements increases, one has to determine the minimum number of elements those can be used to obtain the accurate solution. Therefore this work is aimed to study the effect of number of finite elements on the computed result of hydrodynamic journal bearing and to determine minimum number of finite elements to be used in the analysis of the journal bearing.

Simulation methods of Aluminium and CFRP thinwalled tubes subjected to axial compression and filled with Aluminium foam was investigated in this thesis project. For the Aluminium tube and Aluminium foam, *MAT_3 and *MAT_63 were employed respectively to execute the simulations of the empty and filled tube. To obtain the ideal element size for the mesh, a theoretical method was used to correlate the results with the numerical values obtained in LS-DYNA software. For the CFRP tube, the Finite Element (FE) model was built based on the twolayer shell model, using the *MAT_54/55 material formulation, failure strategy and the parameters sensitivity of the model. Then the simulation model was verified by using duplicate specimens comprised of carbon fibre/epoxy unidirectional prepreg tape. Furthermore, the modelling method of crush trigger B45 and different types of loading speed (static and dynamic) were analysed. A correlation was made between the physical testing results and the numerical values obtained from LS-DYNA to define the ideal values for the strength parameters.

Sandwich materials are the most important applications of technological composites. Composite material is a structure formed by combining macroscopic meaning of more than one base material for a specific purpose. Sandwich materials are again in accordance with this definition and different structures are combined without dissolving in order to provide various mechanical properties desired. In this study, stress distributions of two types of support, flat and radial, were investigated. In the results obtained, the ansys was analyzed in the package program by comparing the geometry of the plate and the differences of the support shapes and the cases where the support shape is the same and the plate geometry is different.

Man, starting from the age of civilization, wanted to simplify the processes which he felt difficult while working out in a routine way. Now we are living in the world of technology. We have different fields of study. Engineering is one among such professions which provides students the caliber to deal with the problems in a different way. Almost all the problems of various subjects which we deal in our mechanical engineering have solutions. Finite Element Methods is a subject where we deal with the elements but not the entire body at once. But still it involves a lot of calculations like Matrix multiplications, solving higher order equations etc. We have chosen a topic in Finite Element Methods i.e. Modal Analysis of elements and are working out to get results in a simpler way. In this paper we use MATLAB software to simplify the tiresome calculations involved in Modal Analysis of Stepped bar. The code for solving the problem chosen was written in Mat lab and was tested for different inputs. Even though it is accurate and has a large number of built in functions, it is lagging applications in most of the mechanical fields. The code and the procedure we are presenting here in our paper don’t exist. The program written asks the user for inputs and gives output after making necessary calculations. Finally we are also using ANSYS 11.0 workbench software for verifying the results obtained in the mat lab. KEYWORDS: ANSYS, MATLAB, Modal analysis, mode, frequency.

The roll cage of Baja vehicle can be of various types, comprising a tubular structure of various dimensions, but all complying with the official rulebook issued by Baja SAE India. Since the vehicle is expected to perform in off-road conditions, various static and dynamic forces are applied on the chassis, and during these off-road conditions, the main motive of roll cage is to ensure total safety of the driver and to assemble and mount other vehicle components. The chassis of the vehicle is first designed in Solidworks 2018 and then analysed in ANSYS 2019.

Partial Discharge (PD) phenomena is always related to insulation degradation; affecting the performance of the insulation within an electrical equipment. Modeling of partial discharge (PD) allows a better understanding of the phenomena. In this review paper, a simulation model for spherical cavity within a homogenous dielectric material has been considered. The model is simulated using Finite Element Method (FEM) with the help of ANSYS-software. PD activity within a void in a solid dielectric is influenced by many factors. One of the factors analyzed here is the applied voltage. Different types of the applied voltage yield in different PD patterns and the conditions for failure of insulation to occur. The applied voltage that is considered here is AC sinusoidal voltage. The obtained result may improve an understanding on PD behavior under applied voltage; also assist in insulation diagnostics.

A beam is a structural member. In this paper a two dimensional Finite Element (FE) model for Mild Steel material as beam has been developed to study. This research work aims to analyze the static analysis of an isotropic rectangular beam with boundary condition and different types of point load. For this, commercially available Finite Element software ANSYS 12.0.1 has been used. Simulation results are critically studied and salient conclusions have been drawn. The outputs of finite element simulation are used to investigate the effect of point load on product integrity and mechanical properties.
