【摘要】 本文为了研究先进命中及高效毁伤弹药 (AHEAD)开舱距离对毁伤效能的影响 ,首先分析了该弹开舱后的子弹散布规律以及单发及点射后形成的交汇平面上子弹密度分布 ,然后建立了弹丸对目标的毁伤评估模型 ,最后采用蒙特卡罗方法以典型目标 (反辐射导弹 )为例进行了计算。计算结果表明 :当目标的散布小于弹丸的散布时 ,毁伤概率随开舱距离的增加而递减 ;当目标散布大于弹丸散布时 ,毁伤概率随开舱距离的变化曲线出现一个峰值 ,该值对应的开舱距离就是相应散布下的最佳开舱距离 ;目标的散布越大 ,开舱距离对毁伤概率的影响越明显更多还原

【Abstract】 In order to study the influence of the split distance of the ammunition “AHEAD” to its damaging efficiency, spacial distribution of sub-projectiles after separation of the shell and the density distribution of sub-projectiles resulting from single and multiple firing in the interception plane were analyzed. The damage assessment model of the projectile to the target was then built up. Damage to a typical target (ARM) was calculated using the Monte Carlo process. The result shows that the damage probability decreases with the increase of the split distance when the target′s distribution is less than that of the projectile′s. On the other hand, the damage probability will assume a peak value when the target′s distribution is more than that of the projectile′s. This peak value is the optimal split distance. The result of calculation also shows that the split distance will have the more obvious influence to the damage when the target′s distribution become wider apart.更多还原
