摘　　要：针对破片杀伤战斗部破片参数的优化设计问题,对破片飞散特性以及对薄靶板的撞击和侵彻行为进行了分析,基于目标靶板毁伤的整体和局部分析提出了破片冲塞式破坏目标靶板能量消耗和比动能的双目标毁伤准则,并建立了战斗部破片参数优化分析模型。最后通过引入遗传算法对破片打击薄靶目标消耗的能量和毁伤概率进行了估算,表明该模型可有效分析破片长度、直径以及初速对打击薄靶目标的影响,研究结果可为战斗部破片的优化设计提供参考。Aiming at fragment parameters optimization design problem of fragmenting warhead, in this paper, the fragment flying characteristics as well as the impact and penetration behavior were analyzed. Based on the overall and local analysis of the overload damage of the target board, it put forward the double target damage criterion of the energy consumption of the fragment and the kinetic energy per unit area to the target board, and established parameter optimization analysis model of warhead fragment. At last it estimated the energy consumption to the thin plate target and the damage probability by introducing the genetic algorithm. It showed the model could effectively analyze fragment length, diameter and velocity influence on the thin plate target. The research results can provide reference for optimization design of warhead fragment.
