爆炸破片作用下 舰载导弹战斗部的安全性数值模拟

Numerical Simulations of the Safety of the Shipborne Missiles Warhead in the Blast Fragment

摘要:

文章主要针对爆炸破片作用下,垂直发射系统中舰载导弹战斗部的安全性进行分析,分别讨论了破片的质量、速度、侵彻角度和破片的数量等因素作用下,舰载导弹外防护设置以及战斗部的响应特性。结果表明:在临界起爆条件附近,炸药的点火增长对撞击速度的变化很敏感。同时,入射角对其是否引爆威胁战斗部的影响也很大；当两破片间距小于破片直径时,破片撞击战斗部形成的冲击波会相互叠加,压力峰值增大,更容易引爆战斗部,而当两破片间距大于 1.7倍的破片直径时,此时两破片产生的冲击波叠加效应降低。

Abstract:

The security of the shipborne missile warhead in the vertical launch system was analyzed in the blast fragment.The effect of quality, velocity, angle and numbers on shock and initiation was mainly studied. The results showed that theignition growth of explosives was sensitive to the changes in velocity within the limits of critical initiation condition, andthe angle also made a difference on shock and initiation. When the spacing of the two fagments was less than the diameterof the fragment, the shockwaves formed by shocking warhead would be superimposed, and the pressure peak increased.When the spacing of the two fagments was greater than the 1.7 diameter of the fragment, the effect of superimposing wouldbe reduced.
