Abstract: By the principles of "the most accordance with actual working situation" and "the least simplification" and based on summarization and improvement of past researches, research on crankshaft FE model standardization was carried out. Crankshaft FEA system of parametric 3D integral model was developed based on VC++ and ANSYS interface. Parametric FE modeling and analysis of most type of crankshafts can be well dealt with by this system. Friendly type navigation interface which can lead user to select the structural type of crankshaft and parameter inputting interface which can lead user to input the structural and loading and material property parameters were designed. This system is not only convenient and efficient like an special analysis software but also possesses the strongpoint of stabilization and credibleness like a large universal software.
