Crankshaft is large volume production component with a complex geometry in the Internal Combustion (I.C) Engine. 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 4-cylinder 4-stroke I.C Engine. The modeling of the crankshaft is created using CREO PARAMETRIC 3.0 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. This load is applied to the FE model in ANSYS, and boundary conditions are applied according to the engine mounting conditions. The analysis is done for finding critical location in crankshaft. Stress variation over the engine cycle and the effect of torsion and bending load in the analysis are investigated. Von-mises stress is calculated using theoretical y and FEA software ANSYS. The relationship between n the frequency and the vibration modal is explained by the modal and harmonic analysis of crankshaft using FEA software ANSYS. The stress analysis of a 4-cylinder crankshaft are discussed using finite element method before and after modification in this paper Maximum stress areas and dangerous areas are found by the stress analysis of crankshaft and Deformation of the crank shaft for different materials. The Analysis was done before and after modification at stress concentrated areas with different loads by that the comparison was taken place. In the stress analysis we get the maximum stress values before and after modification. All the obtained values were plotted. Modifications are applied to reduce the stress of the crankshaft and by that the comparison was done with the previous design. By this the appropriate design optimization will be achieved.
