FEM analysis on one-piece crankshaft of fatigue strength and free mode

Shuiping Li

Abstract

The difference between finite element model of portion-piece crankshaft and the actual load model takes a big error to static and dynamic characteristic of Crankshaft.Therefore.Finite element model of one-piece crankshaft is founded,fatigue strength and free mode of crankshaft are analyzed.Compared with portion-piece crankshaft model,one-piece crankshaft model can reflect a more actual static and dynamic characteristic of crankshaft,and the valuable theory basis is provided for crankshaft optimal design.
