摘要(Abstract)：

为了研究破-破型串联战斗部前级装药爆炸对后级装药的影响,采用三维数值模拟的方法,对前级装药爆轰波作用于后级装药殉爆以及两级装药间加装隔板隔爆进行了研究,同时研究了前后级不同间距时前级爆轰波对后级爆炸成型弹丸(EFP)速度及成型的影响。计算得出后级炸药殉爆距离的范围,在两级装药间加装隔板可以有效地减小爆轰波对后级装药的影响,起到隔爆效果。研究认为爆轰波对后级EFP速度的影响近似于某二次函数曲线的变化趋势,该计算结果可为破-破型串联战斗部结构设计提供参考依据。
In order to study the effect of detonation of front charge on rear of perforation tandem warhead,the sympathetic detonation of the rear charge affected by detonation wave of front charge and a clapboard put between front and rear charge were studied by three-dimensional numerical simulation.The velocity and forming of rear explosively formed projectile(EFP) affected by front detonation wave in different distance were also studied.The range of sympathetic detonation distance of rear charge was calculated.The results showed that the effect of front detonation wave on rear charge could be reduced and then prevent the rear charge explosive when there was a clapboard between front and rear charge.The results indicated that the tendency of front detonation wave affecting on the velocity of rear explosively formed projectile was similar to a quadratic function curve.The results could be a reference for structure design of perforation tandem warhead.
