摘　　要：针对多层破片战斗部参数等存在一定的随机性,很难直接用已有毁伤评估方法计算的问题,提出多层破片战斗部对飞行目标毁伤概率的计算方法。该方法根据多层破片战斗部与飞行目标的空间关系,设计多层破片对目标的散布密度函数;分析破片命中飞行目标约束条件,计算破片击穿飞行目标要害舱段概率。仿真模拟得到了不同飞散距离、不同飞散角度区间条件下破片命中飞行目标的数量,表明了多层破片对飞行目标的毁伤概率与破片散布密度、散布范围的映射关系。该模型可为多层破片战斗部打击飞行目标的设计提供理论支撑。For the randomness of the fragment distribution parameters of the hierarchical fragment warhead,it is difficult to directly use the existing damage evaluation method to calculate it.A target damage probability calculation model was established based on the hierarchical fragment dispersion characteristics and the target damage criterion.The dispersion density function of hierarchical fragment to target was designed according to the spatial relationship between fragment warhead and flying target.The number of fragments hitting the flying target under the conditions of different fragment flying distances and different fragment flying angle ranges were obtained,which showed the mapping relationship between the damage probability of the fragments to the flying target and the fragment dispersion density and range.The results provided a theoretical support for the design of hierarchical fragment warhead to the flying target damage.
