前级环形切割器对后端靶板影响的数值仿真

Numerical Simulation on the Effect of Annular Cutter to Following Target

摘要:

利用ANSYS/LS-DYNA软件进行了环形切割器爆炸后对后端靶板的毁伤及环形切割器壳体的破裂过程的数值仿真。仿真结果表环形切割器爆炸后对后端靶板的毁伤中,起主要作用的是环形切割器壳体的端部形成的破片和内侧形成的聚能侵彻体,而聚能侵彻体对靶板的破坏最为严重；基于环形切割器的串联战斗部设计中,需考虑两级战斗部隔爆设计。

Abstract:

The annular cutter damaged following target and its shell breaking, when the explosive was detonated, which was simulated by using ANSYS/LS-DYNA software. The simulation results showed that the fragments produced by the end part of annular cutter shell and the shaped charge projectile produced by inside part of annular cutter shell had the major seriously damage to the following target, the shaped projectile had the most seriously damage to the target, the design of tandem warhead based on annular cutter needed making allowance for the blast-proof between the two warheads.
