复合结构弹头对多层靶的侵彻效能研究

Study on Penetration Efficiency of Composite Structure Warheads to Multi-layer Target

为改善斜侵彻多层靶情况下弹丸的弹道稳定性,设计一种多层复合结构弹头。运用ansys/ls-dyna对复合结构弹头斜侵彻多层靶进行数值模拟,分析弹头结构不同材料组合对弹体剩余动能和弹道稳定性的影响。结果表明:在20°着角下,设计的多层结构弹头具有自砺性;2层和3层结构弹头在弹道稳定性和质量损耗上均明显优于制式弹;设计的多层结构弹头最优方案为2层合金钢结构弹头。该研究可为穿甲弹头结构设计以及小口径枪弹与多层靶的斜侵彻弹道分析提供参考。

For improving projectile ballistic stability under oblique penetration to multi-layer target, design the multi-layer composite structure warhead. Use ansys/ls-dyna to carry out numerical simulation for composite structure warhead oblique penetration to multi-layer target, and analyze the influence of warhead structure with different material combinations on projectile residual kinetic energy and ballistic stability. The results show that, under 20° striking angle, the multi-layer structure warhead has grinding function. The ballistic stability and quality consumption of two-layer and three-layer warhead are better than standard projectile. The optimal scheme of designed multi-layer structure warhead is two-layer alloy steel structure warhead. The can provide a reference and basis for the design of the warrior warhead and the oblique penetration trajectory analysis of the small-caliber bullet and the multi-layer target.
