摘　　要：轧机主传动系统的安全销需要在一定过载的情况下及时断裂以保证设备安全。针对中国重型机械研究院设计成套的冷连轧机现场调试过程中安全销出现的失效问题,对其进行了三维弹塑性有限元的应力应变分析,对今后的设计提出了一些改进意见。In order to keep the equipment safe, the fracture of the shear pin for the main transmission system in rolling mill must occur on time when the system is overloaded. The 3-D elastic-plastic finite element method is used to analyze the failure of the shear pin which appeared in the debugging process of the cold tandem rolling mill designed by China National Heavy Machinery Research Institute Co. , Ltd. Some constructive advices are put forward.
