聚能战斗部水下爆炸载荷特性
|
摘要
为研究聚能战斗部水下爆炸产生的冲击波及侵彻体的载荷特性,建立聚能战斗部水中自由场爆炸及侵彻含水夹层复合靶的数值仿真模型,获得冲击波强度和测点相对位置的关系,研究有、无药型罩下战斗部对含水夹层复合靶的毁伤差别及冲击波、聚能侵彻体的毁伤效果。结果表明:聚能战斗部水中爆炸冲击波强度在相同爆距下与空间位置有关,但差距不大,聚能侵彻体利用炸药的部分能量形成集中于一个方向的强动载荷。
For investigating load characteristic of the blast wave and the penetrator of shaped charge warhead genenated by underwater explosion,the numerical simulation model of shaped charge warhead exploding under free field and penetrating compound target with water interlayer was established.The relation between the blast wave peak pressure and the test location was gained,and the damage difference of the compound target with water interlayer penetrated by shaped charge warhead with and without liner was researched.Experimental investigation under the same condition as above was done.Combined with the numerical simulation results,the damage effect of the blast wave and the penetrator was analyzed.The results show that the blast wave peak pressure of shaped charge warhead exploding underwater is related to the space location at the same distance from explosive,but the peak pressure will not change too much.On the other hand,the penetrator uses part of the energy of the explosive to form a strong dynamic load in one direction.
