Study on Failure Analysis of Crankshaft Using Finite Element Analysis

Crankshaft is one of the crucial parts for internal combustion engine which required effective and precise working. In this study, aim study to identify stress state in crankshaft explain failure automotive fatigue life by using finite element analysis. The 3D solid modelling model was designed developed SolidWorks. A static structural dynamic analysis on an L-twin cylinder were used determine maximum equivalent total deformation at critical locations crankshaft. tested under loading conditions life, safety factor, alternating damage tool. results obtained from indicated that has obvious crack belongs fracture. fracture only attributed propagating initiate cracks edges lubrication hole cyclic bending torsion. Overall, safe both loadings. analysis, frequency response curve should be avoided it may cause
