摘　　要：三轮摩托车在行驶过程中经常出现曲轴断裂现象,影响了客户的使用安全及企业的声誉.采用有限元软件,对三轮摩托车发动机的曲轴进行静力分析,找到了曲轴应力最大的部位,这与实际断裂的情况吻合.对曲轴产生最大应力部位的结构参数进行改进,并对曲轴材料进行了调整,取得了较满意的结果.The fracture of the three wheeled motorcycles crankshafts greatly affects customers use and corporate repu- tation. This paper carries out the static analysis of engine crankshaft by the finite element software, and found out the fracture position which is consistent with the actual fracture position. Crankshaft structural parameters of the fracture position have been modified and the material has been adjus- ted which reaches a satisfied result.
