    摘要:

    针对同一成型装药形成多模毁伤元问题,利用LS-DYNA动力有限元程序,采用流固耦合方法,对在药型罩前加装一刻槽圆环形成带尾翼爆炸成型弹丸(explosively formed projectile,EFP)的成型过程进行了数值模拟,结果表明,该装药结构能形成带有8个尾翼的EFP,带尾翼EFP的长径比是EFP长径比的2.75倍,其头部速度比EFP增加了15%,实现了带尾翼大长径比EFP和EFP两种模态的转换。

    Abstract:

    In order to study the multimode penetrators with the same shaped charge, the numerical simulation of the forming process of the explosively formed projectile (EFP) with fins which was formed by a grooved torus in front of the liner, was carried out by the Arbitrary Lagrange-Euler(ALE) method using LS-DYNA. Results indicate that the charge structure can form EFP with eight fins, and the length-diameter ratio of EFP with fins is 2.75 times of that of EFP and it velocity increases by 15 percent.
