摘　　要：为解决常规药型罩破片群成型中存在的径向发散不足的问题,对传统的成型弹体结构进行了改进,并对药型罩破片群的成型过程进行了数值仿真,最后通过靶板效应实验进行了验证。研究结果表明,药型罩破片群的径向发散能力得到了有效增强,形成的破片群径向散布角达到18°。In traditional forming technology of liner fragments, radial dispersion of liner fragments is limited. To solve this problem, the traditional structure of shaped charge war- heads was improved. Simulation of the forming progress of liner fragments was done, and the forming effects were validated experimentally. It is concluded from the results that the ability of radial dispersion of liner fragments is enhanced, and the radial dispersion angle of liner fragments reaches 18°.
