摘要
复式攻坚侵彻弹是以地下或深层掩体为攻击目标的武器。针对前级聚能侵彻装置必须在目标混凝土外层侵出一个一定直径和深度的孔的问题,进行优化研究。针对影响侵彻孔径和深度效能优化难题,通过应用LS-DYNA软件对设计的掘进武器前级聚能侵彻装置的主要参数,对药型罩的锥角变化以及壁厚和起爆位置等主要影响因素,对前级聚能射流对其产生的射流形状、速度和侵彻效果结合相关理论进行分析,通过侵彻仿真分析,得出了为攻坚战斗部的前级开孔工作优化的参数设计依据,通过侵彻数值仿真,选择了最佳的设计方案,为攻坚战斗部的进一步优化设计提供了参考依据。
Composite penetrator warheads are the weapons which treat underground or deep shelters as attack tar gets. The research carried out the optimization study to make precursory shaped charge penetration device capable of penetrating a hole of a certain depth and diameter into the outermost layer of target shields. In order to solve the opti mizing problems of penetrated pore＇s diameter and depth, the software LS DYNA was applied to analyze the main parameters for design driving weapons＇ precursory shaped penetration device and some important influences, such as cone angle changes in shaped charge liner, wall thickness and initiation position, and so on. And with related theo ries, we analyzed the jet shape, speed and penetration impact that the precursory shaped jet has generated. Through the analysis of penetration simulation, the parameter design basis was obtained for warhead to do precursory holing. Based on the penetration numerical simulation, the best design plan can be decided, and it will provide a reference for warhead to get a further optimization design.
