聚能战斗部对双层靶板结构毁伤的数值模拟研究

摘要

The neotype shaped charge warhead is one of the most promising types of efficient damage war⁃heads,which is gradually becoming a research focus globally. In this paper,the penetration process pro⁃duced by a shaped charge warhead is simulated with the LS-DYNA software. An approach based on the rel⁃ative penetration depth is proposed to evaluate the structural damage capabilities of the warhead. Also, some real explosion test data regarding the perforation size and penetration depth is employed to verify the numerical simulation results. It is found that the presented method is applicable in designing neotype shaped charge warheads.%　　新型聚能装药战斗部是高效毁伤战斗部的发展方向之一，已成为各国研究的重点。利用 LS-DYNA 软件，对聚能战斗部侵彻过程进行数值模拟，提出一种利用相对侵彻深度定义结构毁伤等级，进而表征聚能战斗部毁伤能力等级的评估方法，并利用实爆试验测量的穿孔大小和侵彻深度对数值模拟结果进行验证，该研究方法能够为设计新型聚能装药战斗部提供参考。
