摘要

链条拆节设备的撞针在载荷反复作用下极易发生疲劳损坏，威胁链产品质量。为了研究撞针疲劳破坏的规律，利用Workbench软件对撞针进行有限元分析，首先通过静强度分析确定撞针结构的薄弱部位，在此基础上进行疲劳寿命计算，获得撞针的疲劳寿命情况。将分析得到的数据与实际验证情况进行对比，结果表明，两种方法的效果基本一致，从而验证了有限元分析的有效性，也为后续设备维护和结构优化提供了一定的技术参考。

Abstract

The firing pin of chain demolition equipment are prone to fatigue damage under repeated loads， threaten the quality of chain products. In order to study the rule of firing pin fatigue damage， using the workbench software to perform the finite element analysis of the firing pin. Firstly， through the static strength analysis， the weak parts of the firing pin are determined， on this basis， the fatigue life is calculated， and the fatigue life of the firing pin is obtained. Comparing the data with the actual verification， the results show that the effect of the two methods is consistent and the validity of the finite element analysis is verified， it also provides some technical reference for the following equipment maintenance and structure optimization.
