摘　　要：破片聚焦战斗部威力设计通常针对静爆条件,但在实战条件下,由于弹目相对速度和战斗部沿轴线方向破片初速梯度的影响,破片动态飞散角将重新合成,导致聚焦破片散开,破片在靶面的分布密度大为降低(可降低到静态条件的1/2)。采用射击迹线法对破片聚焦战斗部在静爆和动态条件下的破片飞散过程和破片在靶面的分布密度进行了仿真研究,提出了破片聚焦战斗部的动态杀伤威力设计概念,以破片平行聚焦战斗部为例给出了动态杀伤威力的实现方法。The design of focused fragmentation warhead is generally based on the detonation test in the static situation. In actual combat, because of the warhead velocity relative to the target and the fragments initial velocity gradient in existence along the warhead axial, the fragment dynamic ejection angle will be recomposed, the fragment clustering may disperse, and the fragment density on the target will decrease greatly. The simulation of the fragment ejection process and the fragment hitting density on the target under the situation of static detonation and actual combat shows that, the dynamic lethality for focused fragmentation warhead can be achieved at typical interception condition. As a result, a concept of the dynamic lethality for focused fragmentation warhead is developed. The method fulfilling the design of the fragment dynamic focusing for a parallel-focusing fragmentation warhead is given.
