摘要
针对来袭目标导弹战斗部通常靠高速破片冲击引爆战斗部从而达到毁伤效果,但是靠一味地增加破片速度来冲击引爆战斗部已经受到限制。对一种新型复合结构破片(即含能破片)引爆模拟战斗部进行了研究,基于平头柱形含能破片撞击带铝壳炸药的模型,采用数值模拟的方法,研究了含能破片引爆带壳炸药的基本规律,给出了柱形含能破片引爆带壳炸药的速度区间,结果表明含能破片可以大大降低引爆盖板装药的速度。
For the incoming target missile warhead fragments often rely on high-speed impact damage detonated warhead so as to achieve results, but by blindly increasing the speed of the impact of fragmentation warhead detonation has been restricted. A new type of composite structure containing fragments that can detonate simulated warhead fragments were studied, based on the model of the covered charge impacted by flat-nose cylindrical energetic fragments, the impact mechanism was studied by numerical simulation. The detonated velocity range of the flat-nose cylindrical energetic fragments was proposed. The results show that the energetic fragments can significantly reduce the velocity of detonation of the cover charge
