M.N.V Krishnaveni, M.Amareswari Reddy, M RajaRoy Crane hooks are highly liable components that are typically used for industrial purposes. Failure of a crane hook mainly depends on three major factors i.e. dimension, material. In this paper load carrying capacity is studied by varying the cross sections. The selected sections are Circular, Trapezoidal and T-section. The area remains constant while changing the dimensions for the four different sections. The crane hook is modelled using SOLIDWORKS software. The stress analysis is done using ANSYS 14.0 workbench Educational version. It is found that T cross section yields minimum stresses at the given load of 6ton for constant cross section area among three cross sections. The stress distribution pattern is verified for its correctness on model of crane hook using Winkler-Bach theory for curved beams.Three

The rail-wheels are subjected to more contacts stresses of alternate magnitude due to roll-actions of the wheels under these types of loads. these types of rails are able to sustain types of varying loads for there future scope or unlimited life. There are some Accidents are occurring due to fractures of the rail-wheels & it effects on the safety of railway facilities. Therefore, large more advertence is giving to the qualities of the rail-wheels. The railways are of wheels failed due to the sum of reasons there are fatigue under the type of loadings where as other mode of failures is damage of rail-bogie, suspension failures and in case of derailment of the vehicles. Therefore, after all advancement in designs, material and non-destructives inspections, the fatigue propagation and failures due to the damages of railway components is a one of the issues for those safety engineer peoples in railway. In this research work, a bid is made to inquest the fact of stresses in the rail wheel assembly due to the more contact load at the assemblies' points. The work here shows the culminate of stress von-Mises, strain & safety factor using finite element kitler on ANSYS 16.0. A well-turned sage of these mechanism needs in depth knowledges of physical-interaction between rails and wheels. The rail wheel assembly is assumed to operates under the designed loads. The Goodman-mean-stress-correction theory is used to attain the results. The result on the fatigue-life are shows here, which are assumed to depend on these factors

Experimental Validation & Redesign of Wheel to Improve the Strength to Withstand the Operating Load
International Journal of Advanced and Innovative Research, 2016
Wheel is used in combination with axles used in facilitating transportation. Wheels are used in different applications. In this project we are concerned with improving the strength of the wheel to withstand the operating load. The wheel has to pass different tests before it is put into operation. Axial compression test and cornering fatigue test are the important tests among them and fatigue life of the wheel is calculated. The problem occurring with the base model of the wheel is studied firstly. The automotive wheel has to meet certain load carrying capacity during operation should and should adhere to some running conditions. But wheel manufactured sometimes will be unable to carry the expected loads and this must be validated with experimental results using FE methods. If the model is failing then one has to develop conceptual designs which are having more strength than previous design. And these models are checked numerically whether these designs are better than base design or not. A best design is suggested among these models which is having more strength than base design.
Designing of railway wheels. Part 1: finite element method
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2005
Current design processes can be simplified and accelerated if computer simulation based on finite element method (FEM) is used. FEM numerical calculations of different wheels of railway wheelsets are investigated in the Department of Railway Engineering. The justification for undertaking this issue is that there is no methodology in the design of railway wheelsets both in Poland and abroad; there is no possibility of optimizing wheelsets' construction characteristics depending on manufacturing process and service parameters. The analysis of this problem has made possible: (a) comparison of software used so far in strain calculation of railway wheelsets; (b) elaboration of design methodology for railway wheelsets; (c) increase in durability of railway wheelsets; (d) increase in the safety of rail transport; (e) decrease in manufacturing and service costs of railway wheelsets.
GEOMETRICAL OPTIMIZATION AND EVALUATION OF ALLOY WHEEL FOUR WHEELER Problem Description
Previously steel wheels are used to manufacture wheels for the higher strength, but these alloy wheels are heavily due to its density and also giving trouble to manufacture because of its higher melting point and hard to do casting it. Weight is also playing crucial role in mileage. After that aluminum and magnesium took the place for the manufacturing of alloy wheel, but these alloy wheels are not giving good life due to its low compressive and yield strength.

In automobile industry it is essential to produce the light weight assembly in order to increase the vehicle performance. Also, lots of forces during braking, acceleration and bump conditions are also applied directly during dynamic condition. So, the project is concerned with design, analysis and manufacturing of knuckle and hub. The objective of this paper is to reduce weight and increase performance of vehicle. This paper deals with calculation of various loads and their simulation. We also have used the lotus to find the hard point of the knuckle to improve the steering geometry as well as the suspension geometry of vehicle. The FEA result indicates that the upright assembly is able to perform safely in real track condition as per performance requirement. It must also be noted that the components must be designed in such a way that they have a minimum weight at the same time care must be taken that they do not cross a certain limit of stress value. In this Project, the Complete Design Procedure of the Wheel Assembly for AT-111 Rims with Tires (23*7*10) has been presented along with the optimization of the same components. The weight of the vehicle is considered to be 300 kg along with the driver. The project illustrates the forces acting on the components, the failure criteria, and the optimization of the components. The project deals with finding out the dimensions of the individual components and also detecting the probable regions of stress concentration.

Design And Analysis Of Train Wheel And Rail DESIGN AND ANALYSIS OF TRAIN WHEEL AND RAIL
Now a day's effort has been made to optimize Wheel and rail design to improve the performance and reduce the cost. These trends have changed the major wheel rim damage from wear to fatigue. The major cause of rolling resistance lies in the slippage between the wheel and the surface, which dissipates energy. Factors that contribute to rolling resistance are the deformation of the wheels, and movement below the surface. In this paper, a detailed overview of the rolling contact problem of train wheels was given by different failure modes have been observed for train wheels in rim damage, train suspensions. The rolling contact of a wheel on a rail is the basis of many Rail-Wheel related problems including the rail corrugation, wear, and plastic deformation, rotating interaction fatigue, thermo-elastic-plastic-behaviour in contact, fracture, creep, and vehicle dynamics vibration.
