摘　　要：为评估破片战斗部对武装直升机的威力,提出了一种将目标舱段等效划分为几何/结构舱段、要害舱段和非要害舱段3种类型的易损性模型,针对不同的舱段类型制定了不同的毁伤评估准则和毁伤概率计算方法.引入基于THOR方程的射击线仿真,考虑了空气阻力导致的破片着靶点漂移效应,以及破片对多层舱段的穿透破坏作用.利用对起爆位置均匀抽样仿真的方法,得出了破片战斗部对典型目标的毁伤空间分布规律,结果表明目标要害部位分别位于主旋翼和尾桨附近,从顶部攻击时效率更高.To assess the lethality of fragment warhead to armed-helicopter,a vulnerability model of typical target was proposed,which contained geometric/structural components,vital components and non-vital components,and the corresponding damage criterions were also set.The shot line simulation based on THOR equation was introduced,which considered air resistance and multi-part penetration effect of fragments.Based on uniform sampling of explosion position.The spatial distribution of fragment warhead damaging typical target was obtained.The result indicates that the vital region locates near main rotor and tail rotor,and it is more efficient to attack target from top.
