为了提高串联随进战斗部前级聚能装药结构对混凝土介质的破坏威力。文中利用LS-DYNA有限元分析软件对一种星锥状药型罩聚能装药结构形成射流侵彻混凝土靶板的过程进行数值模拟,分析了其成型过程以及对混凝土靶板的侵彻结果。通过与传统单锥状药型罩聚能装药结构形成射流侵彻混凝土靶板数值模拟结果的对比,表明由星锥状药型罩所形成的射流对混凝土靶板具有更强的破坏能力。为新型复合战斗部的前级聚能装药结构设计提供了依据。

In order to improve the destructive power of the structure of forward shaped charge and explosion proof body for tandem warhead on concrete medium, the LS-DYNA was used to perform numerical simulation on the process that a structure of the new star shaped liner forms jet penetrating concrete target in order to analyze the forming process whereof and the penetrating result on the concrete target Comparing the numerical simulation result with that of the formation of the jet penetrating concrete target formed by the traditional shape charges structure, the jet formed by the new star shaped liner has stronger destructive power on the concrete target, which lays the foundation for the structure design of the new tandem warhead shape charge.
