为了为聚能装药战斗部结构设计或优化提供参考,利用ANSYS/LS-DYNA有限元软件,采用ALE方法,就其中壁厚类型不一样的三类药型罩结构侵彻靶板过程展开了探究。仿真结果表明:在一定壁厚范围内,随着药型罩壁厚的增加,有利炸高呈现出较高的稳定性;壁厚相同时,破甲深度随炸高的增加呈现出先增大后减小的趋势。研究结果对于聚能装药战斗部在工程方面的应用具有一定的指导意义。

In order to provide references for the design or optimization of shaped charge warhead structure, the ANSYS/LS-DYNA finite element software and ALE method were applied to explore the penetration process of three kinds of liner structures with different wall thickness types. The simulation results show that in a certain wall thickness range, with the increase of liner wall thickness, favorable height of burst shows relatively high stability; when the wall thickness is the same, with the increase of the height of burst, the penetration depth increases first and then decreases. The research results have certain guiding significance for the application of shaped charge warhead in engineering.
