为研究高速钨合金穿甲弹对超音速导弹战斗部的冲击起爆特性,应用Lee-Tarver点火增长模型进行了数值模拟,获得了钨合金穿甲弹冲击起爆超音速导弹战斗部的机制以及弹目交汇角对冲击起爆的影响规律。结果表明:钨合金穿甲弹对超音速导弹战斗部的冲击起爆,发生在穿甲弹绝热剪切装药的阶段;偏轴距离相同,冲击起爆超音速导弹战斗部的能力,先与入射角大小成正比,后成反比;入射角相同,偏轴距离越小,冲击起爆超音速导弹战斗部的能力越强。

In order to study the characteristics of impacted initiation of high-speed tungsten heavy alloy penetrator for supersonic missile warhead, Lee-Tarver ignition and growth model was used for numerical simulation, the mechanism of tungsten heavy alloy penetrator impacting initiation on the warhead of supersonic missile and the influence rules of the intersection angle on impact initiation were got. The results show that impacting initiation of the tungsten heavy alloy penetrator on supersonic missile warhead occurs when the penetrator adiabatically shears the explosive; For the same off-axis distance, the capabilities of impacting initiation of the tungsten heavy alloy penetrator on the supersonic missile are in direct proportion to the incidence angle and then in inverse proportion; As for the same incidence angle, the smaller of the off-axis distance, the bigger of the abilities of impact initiation of tungsten heavy alloy penetrator on supersonic missile.
