摘　　要：将轿车三枢轴式等速万向节的三维模型经过结构简化离散成有限元模型,并应用ANSYS软件对其承受极限转矩时的内部接触应力进行有限元分析。结果表明,三枢轴式等速万向节枢轴上的接触应力大,易磨损,疲劳寿命短。最后对万向节的设计和加工提出改进措施。A finite element（FE） model for a tripot universal joint is developed, and a FE analysis on the contact stresses in the parts of the joint under extreme torque is conducted using ANSYS software. The results indicate that the maximum contact stress appears on the pivot shaft, where the serious wear and fatigue also easily occur. The improvement measures in design and machining are put forward in the end.
