Crankshaft is one of the critical components for the effective and precise working of the internal combustion engine. This converts the reciprocating displacement of the piston in to a rotary motion of the crank. An attempt is made in this Project is to study the Static analysis on a crankshaft from a 4 cylinder I.C Engine. A threedimension model of IC engine crankshaft is created using CATIA V5 software. Finite element analysis (FEA) is performed to obtain the variation of stress magnitude at critical locations of crankshaft. Simulation inputs are taken from the engine specification chart. The Static analysis is done using FEA Software ANSYS which resulted in the load spectrum applied to crank pin bearing. 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 Shear Stresses are calculated using theoretically and FEA software ANSYS
