摘　　要：扭杆是剪切机中的关键零件，在剪切过程中受交变裁荷作用，在实际生产中常出现疲劳断裂现象。本文利用有限元对某厂冷剪机的拉杆进行疲劳分析，结果表明，在剪切力发生倾斜条件下，拉杆强度不能满足疲劳寿命长时间运行要求，有可能引起疲劳断裂。The rod is a key part in the shearing machine. In the process of production , there often occurs a phenomenon of fatigue fracture , for the rod is going through stresses which change often in shearing process. In this paper , using the finite element analysis to study the fatigue of the rod , we get the results that the strength of the rod can not meet the requirements of a long run , and may lead to fatigue fracture when it is in the beveled cnld shearing machine.
