3-D Finite Element Analysis on 480 Diesel Crankshaft

Finite element analysis has been used to investigate the vibration modal of 480 crankshaft and the stress analysis of crankpin. The aim of the modal analysis was to explain the relationship between the frequency and the vibration modal. And the aim of the stress analysis of crankpin was to find the maximum deformation and maximum stress point. In this paper, three-dimension models of 480 diesel engine crankshaft and crankpin were created through Pro/ENGINEER software. The finite element analysis (FEM) software ANSYS was used to analysis the vibration modal and the distortion and stress status of the crankpin. The results of crankshaft vibration modal were calculated. And the stress figures of 480 diesel engine crankpin were calculated, combined with maximum stress point and the dangerous area. The results would provide valuable theoretical foundation for the optimization and improvement of engine design.
