摘　　要：为进一步提高轴向多爆炸成型弹丸战斗部对轻型装甲车辆及人群目标的毁伤威力,采用LS-DYNA数值仿真软件,研究隔板厚度、隔板直径、罩顶药高及材料对轴向端面MEFP成型特性的影响规律。随着隔板厚度和直径的增加,MEFP的头部速度及长径比增加,周边EFP的飞散角明显减小;随着罩顶药高的增加,MEFP的头部速度和长径比显著增加,周边EFP的飞散角无明显变化;隔板材料密度的改变主要影响MEFP的速度和长径比。In order to further improve the damage capability of axial multi-explosive shaped projectiles warhead to light armored vehicles and crowded targets,LS-DYNA numerical simulation software was used to study the influence law of waveshaper thickness,diameter,apical charge height and material on the forming performance of MEFP.The results show that the head velocity and slenderness ratio of MEFP increase with the increase of the thickness and diameter of the waveshaper,while the EFP scattering angle decreases obviously.The head velocity and length-diameter ratio of MEFP increased significantly with the increase of apical charge height,but the scattering angle of EFP did not change significantly.The change of material density mainly affects the velocity and slenderness ratio of MEFP.
