Design,Analysis and Optimization of crankshaft using CAE

ABSTRACT Crankshaft is one of the critical components for effective and precise working of the internal combustion engine. The main objective of this paper involves modeling, analysis of crankshaft, so as to identify the effect of stresses on crank shaft and to find optimum design parameter of existing crankshaft. The modeling software used is CATIA for 3D modeling of crankshaft .The analysis software HYPERMESH is used for linear static analysis of crankshaft.Optisrtuct solver is used for finite element analysis of crankshaft. The materials for crankshaft on which analysis was done SAE1052, SAE1045, SAE 1137 and SAE1055 etc.
