以双层药型罩形成的串联爆炸成型弹丸(EFP)为研究对象,运用数值仿真软件AUTODYN,对不同材料组成的双层药型罩产生的串联EFP成型与侵彻靶板过程进行数值模拟计算。通过比较双层EFP形状、速度、长径比、动能等参数,得出内外罩材料冲击阻抗之差对于双层EFP侵彻能力的影响,其侵彻能力最强的材料组合为外钽内铝组合。

In this paper, the object of the double-layer shaped charge(DLSC)into tandem explosively formed projectile (EFP)was studied. And AUTODYN was used to carry out the numerical simulations about penetrating target for different liner materials combinations on the formation of tandem EFP. By comparing the formation, velocity, length-diameter ratio and kinetic energy of DLSC into tandem EFP, a result was obtained that the impact impedance of different liner materials combinations affected the penetrating ability of the DLSC into tandem EFP and the study showed the best materials combi-nation was Al-Ta.
