为了优化不同起爆方式下产生的爆轰波对定向战斗部毁伤效能的影响。利用LS_DYNA有限元仿真软件,模拟研究了在不同起爆方式下战斗部爆轰波压力场的分布规律和破片的飞散规律。仿真结果表明:随着起爆线夹角的增大,定向区域范围逐渐减小;随着起爆线的增加,定向区破片速度增大,定向区域范围基本无变化。起爆线夹角大于60°时,可以采用等距起爆的方式改善稀疏波的影响和增大定向区域破片的速度;起爆线夹角选取30°~60°范围,更有利于发挥战斗部的毁伤效应。

In order to optimize the impact of detonation waves generated under different initiation methods on the damage efficiency of the aimable warhead. Using LS_DYNA finite element simulation software, the distribution law of the detonation wave pressure field of the warhead and the scattering law of fragments under different initiation methods are simulated. The simulation results show that with the increase of the detonation line angle, the directional area gradually decreases; with the increase of the detonation line, the directional area. The fragment velocity increases, and the scope of the orientation area is basically unchanged. When the angle of the detonation line is greater than 60°, the equidistant detonation method can be used to improve the influence of the sparse wave and increase the speed of the fragments in the directional area. The angle of the detonation line is selected in the range of 30°~60°, which is more conducive to exerting the damage effect of the warhead.
