摘　　要：通过对引信保险机构缸体的超动态电阻应变测量 ,搞清了它在弹体穿透防护层时的动态变形规律 ,纠正了对缸体变形的一些错误认识 ,并得到了名义冲击力与应变关系的工程计算方程 ,为对保险机构的设计改进和理论计算 ,提供了可靠的实验依据。In this paper, fuse safety mechanism cylinder is measured by using ultra-high-frequency dynamic strain instrument. Its dynamic deformation regularity is made clear when its defense layer is penetrated by warhead, and the relationshop between strain and shock force under shock load is discussed. So it can provide reliable experimental data for science study.
