摘　　要：为了提高爆炸成形弹丸(EFP)的命中概率,设计了一种新型整体式多爆炸成形弹丸(MEFP)战斗部结构。为验证设计的整体式MEFP战斗部结构的可行性,对其进行了地面静爆试验,并利用LS-DYNA程序对弹丸成形及侵彻45#钢靶过程特性进行了数值模拟,模拟结果与试验结果吻合较好。研究表明,该MEFP战斗部可按预期生成7枚具有一定质量和方向性、可贯穿15 mm厚45#钢靶的弹丸,从而有效地提高了毁伤元的数量和毁伤面积。A new integral multi-explosively formed penetrator （MEFP） warhead is designed in order to improve the hit probability of explosively formed penetrator （EFP）. The feasibility of the warhead structure is verified in static blast experiment. And the processes of MEFP forming and penetrating a target are simulated using LS-DYNA3D. The simulated results coincide well with the experimented data. The result indicates that such a warhead can form seven explosively formed projectiles which have a definite mass and direction and can penetrate a 15 mm-thick 45^#steel target, thereby increasing effectively the number of damage elements and damage area.
