| Abstract: | By means of FEM using ANSYS, a three-dimension model was created through Pro/E for model S195 diesel engine's crankshaft corresponding to practical conditions. The distortion and stress of the crankshaft was investigated. The fatigue strength of crankshaft was verified under changing load. The rationality of crank stress analysis method, which is widely used currently, is discussed. The model analysis was made for the crankshaft, which provides valuable theoretical foundation for the optimization and improvement of engine design. |
