掠飞攻顶反坦克破甲战斗部的动态特性研究
|
摘要
为提高掠飞攻顶反坦克破甲战斗部的侵彻威力,利用仿真软件对掠飞类破甲战斗部的动破甲过程进行数值模拟,在一定的大炸高下,分析了杆式射流的侵彻特性随破甲战斗部的斜置角和横向速度的变化。结果表明:掠飞类破甲战斗部侵彻靶板时存在涂抹效应;破甲战斗部的横向速度在0～200 m/s的速度范围内,设置斜置角可以实现动破甲的威力补偿,横向速度越大,最佳斜置角也应越大;破甲战斗部的斜置角一定,横向速度越大,射流动破甲时的能量损耗越大,横向速度达到300 m/s时,设置斜置角不能实现动破甲的威力补偿。对仿真结果进行了初步试验验证,结果可为掠飞类破甲战斗部研制提供参考。
In order to improve the penetration power of the top flying attack antitank armor warhead,the simulation software was used to simulate the dynamic breaking process of the shaped charge warhead. Under a certain height,the penetration characteristics of the rod type jet were analyzed as well as the change of the oblique angle and the transverse velocity of the warhead. The results show that there is a smear effect when the shaped charge warhead penetrates the target plate,that the oblique angle can achieve the power compensation of the moving armor when the lateral velocity of the warhead is in the range of 0 to 200 m/s,that the greater the lateral velocity,the greater the best oblique angle;and that the more oblique angle of the warhead and the more transverse velocity,the larger the energy loss when the flow is broken,and that when the lateral velocity reaches 300 m/s,the power angle compensation can not be achieved by setting the oblique angle. The simulation results were preliminarily tested and verified,which can provide references for the development of the flying class shaped charged warhead.
