针对某型火箭发射装置武器发射过程中出现的设定头与移动轴剪切变形失效的问题，采用理论计算、模拟试验、射击试验以及分析零件金相组织的方法，对设定装置移动轴受冲击载荷作用下的动态响应和失效机理进行了分析。结果表明：武器发射瞬间的冲击会对移动轴的动态响应时间产生较大的影响，移动轴螺旋压缩弹簧的应力松弛和移动轴的热处理缺陷是引起失效的主要因素。

To solve the shearing deformation and failure problem caused by the collision between the setting top and the shifting axis during the weapon launching of a rocket launcher ,this paper makes an investigation into the dynamic response and failure mechanism of the shifting axis of the setting de-vice under the impact load by theoretical calculation ,simulation test ,shooting experiment and metal-lurgical structure analysis .The results show that the weapon launching impacts have a large influence on the dynamic response time of the shifting axis .The stress relaxation of the helical spring and the defect in the heat treatment of the shifting axis are found to be the main factors of failure .
