This converts the reciprocating displacement of the piston in to a rotary motion of the crank. We are study selection of best material by comparing the Static analysis on a crankshaft from a multi cylinder (4-cylinder) 4stroke I.C Engine. The modeling of the crankshaft is created using CATIA-V5 Software. This model will be converted to Initial Graphic Exchange Specification (IGS). Finite element analysis (FEA) is performed to obtain the variation of stress at critical locations of the crank shaft using the ANSYS software and applying the boundary conditions. Then the results are drawn Von-misses stress induced in the crankshaft is 15.83Mpa and shear stress is induced in the crankshaft is 8.271Mpa. The Theoretical results are obtained vonmisses stress is 19.6Mpa, shear stress is 9.28Mpa. The validation of model is compared with the Theoretical and FEA results of Von-misses stress and shear stress are within the limits. Introduction: Crank shaft is a large component with a complex geometry in the I.C engine, which converts the reciprocating displacement of the piston to a rotary motion with a four bar link mechanism. Crankshaft consisting of shaft parts, two journal bearings and one crankpin bearing. The Shaft parts which revolve in the main bearings, the crank pins to which the big end of the connecting rod are connected, the crank arms or webs which connect the crank pins and shaft parts. In addition, the linear displacement of an engine is not smooth; as the displacement is caused by the combustion chamber therefore the displacement has sudden shocks. The concept of using crankshaft is to change these sudden displacements to as smooth rotary output, which is the input to many devices such as generators, pumps and compressors. It should also be stated that the use of a flywheel helps in smoothing the shocks. Crankshaft experiences large forces from gas combustion. This force is applied to the top of the piston and since the connecting rod connects the piston to the crank shaft, the force will be transmitted to the crankshaft. The magnitude of the forces depends on many factors which consist of crank radius, connecting rod dimensions, and weight of the connecting rod, piston, piston rings, and pin. Combustion and inertia forces acting on the crankshaft  Torsional Load  Bending Load Crankshaft must be strong enough to take the downward force of the power stroke without excessive bending so the reliability and life of the internal combustion engine depend on the strength of the crankshaft largely. The crank pin is like a built in beam with a distributed load along its length that varies with crank positions. Each web is like a cantilever beam subjected to bending and twisting.  Bending moment which causes tensile and compressive stresses  Twisting moment causes shear stress

The proper position of a cutout in a rectangular plate can be significantly affected by the choice of material, cutout size, and various end conditions which are relative to the externally applied force. The research work entitled in this paper deals with the finite element formulation applied to a plate made with isotropic and laminated plates subjected to uniform pressure with various end conditions. The vicinity of stress distribution for the rectangular plate made of these two materials with and without the effect of circular cutouts is discussed. The accuracy of the solution verified with the available literature, and from the comparison, a fairly good agreement seen between the Finite element formulations in this paper with previously available results.

This machine is driven by using a single mechanism for an operation. Here the focus is on the Geneva wheel which is used for this respective operation. Geneva Wheel mechanism here rotates and the index the roller in the conveyor belt one by one step. As we know there is the major drawback of a Geneva mechanism that jerk a lot while the operation is in process due to which it loses its acceleration. Here a symmetrical coupler curve of 4 bar mechanism which run on a Dwell curve is added to avoid the jerk as low as it can. The forces are analysed on the simulated mechanism with meshing method and the result to be presented in a graphical order, which represent the Von Mises stress and displacement.

In this study, the importance of sensitivity is discussed, as high sensitiveness leads to poor unexpected performance. For better orientation and position of robot end effectors, the sensitivity analysis of the robot is needed, with the proper position of robot can work effectively comparatively less cost.

The significant effect of loading on the pre-twisted curved blade are evaluated in terms of its deflection and corresponding stresses. A more simplified approach was not satisfactory and furthermore to establish the feasibility of composite blade detailed stress analysis has been carried out for various pre-twist angles of composite and mild steel blade using a thick shell element. The suitability of the finite element method in predicting the stresses in externally loaded laminates is examined from the viewpoint of satisfaction of all boundary conditions and results. From the results it can be shown that the three-dimensional finite element analysis provides a useful insight for predicting deflection and stresses. The influence of ply angle for the distribution of inter laminar stresses along y...

Wear studies are carried out using PIN ON DISC APPARATUS. Weight loss of composites during abrasion has been examined as a function of sliding distance, normal load and weight fraction of graphite. Specimens with varying weight fraction of 10, 15, 20, 25, 30 of graphite have been taken and wear test is conducted using pin on disc apparatus under dry contact conditions. Weight loss is determined for loads of 10N, 20N, 30N with a track diameter of 40 mm, disc rotating speed of 500 rpm, using 400 grade silicon carbide emery papers. A series of experiments are conducted to find out the weight loss due to wear and thus estimate the specific wear rate coefficient of each specimen using " ARCHARD'S EQUATION ". Graphs are plotted to show the variation of weight loss with abrading distance, with increase in graphite percentage at various loading conditions and variation of specific wear rate against applied load with increase in graphite percentage at various abrading distances
