摘要/Abstract

摘要： 应用ANSYS/LS-DYNA软件研究了刻槽式多爆炸成形弹丸（MEFP）对双层有限厚钢靶侵彻能力及后效,得到了刻槽式MEFP战斗部对双层有限厚钢靶侵彻及后效的效果图。结果表明：装药长径比对弹丸成型后的形状影响较小，刻槽深度对弹丸成型后的形状影响显著；其他条件不变时,药型罩厚度增加使弹丸轴向速度减小，进而增加了药型罩侵彻时的侵蚀量，因此从侵彻深度角度考虑，药型罩厚度存在最优值；从整体看，刻槽深度较浅的战斗部后效较好。计算结果与试验结果基本一致。

Abstract: The penetration ability and aftereffect of multiple explosively formed projectile (MEFP) with scored liner to a finite thick double-layer steel target are analyzed using ANSYS/LS-DYNA. The results show that the length-to-diameter ratio of charge has little effect on projectile shape, and the groove depth has a significant effect on projectile shape. If other conditions remain unchanged, the increase in thickness of liner leads to the reduction in axial speed of projectile, increasing the erosion amount of liner. Therefore the liner has an optimal thickness value in view of penetration depth; the aftereffect of shallow groove depth is better. The simulation results are consistent with the experimental results.
