串联爆炸成型弹丸外弹道特性仿真

摘要
建立了前、后级爆炸成型弹丸飞行速度的理论计算模型,利用LS-DYNA对双层EFP的飞行过程进行数值模拟。研究结果表明:在一定条件下,前后级EFP可以实现已分离的串联EFP在后续飞行至一定位移处追击重合。
A theoretical calculation model of the front and rear Explosively Formed Projectile(EFP) flight speeds was established,and the flight process of the double-layer EFP was numerically simulated using LSDYNA. The results show that under certain conditions,the front and back EFPs can achieve the follow-up flight of the separated EFPs to a certain displacement.
