Abstract:

A fish bone diagram (see fig. 1.2) is developed to study the root cause analysis of crankshaft failure. The objective of this study is to find stress magnitude at critical locations by using finite element analysis. In this study a dynamic simulation is conducted on forged steel crankshaft of six cylinder four stroke diesel engine. The dynamic force analysis is carried out analytically. The load is then applied to the FE model in ANSYS and boundary conditions are applied. Considering torsional load in the overall dynamic loading conditions has no effect on von Mises stress at the critically stressed location. The effect of torsion on the stress range is also relatively small at other locations undergoing torsional load. Therefore, the crankshaft analysis could be simplified to applying only bending load. The principal plane stresses obtained by using finite element analysis are compared with normal stresses obtained by theorotical calculation. Also vonmises stress is calculated theoretically and compared with finite element analysis (ANSYS) results
