摘　　要：为了解决在大块度障碍物上快速开孔且孔深和孔径符合要求的难题,提出了一种前后两级均为爆炸成型弹丸装药的新型串联聚能装药结构。利用LSDYNA3D有限元软件对串联EFP装药的药型罩成型过程进行了数值模拟,并分析了两级装药间距对后级EFP成型的影响,在此基础上开展了串联EFP装药侵彻45#钢靶试验。结果表明,该串联EFP装药结构可充分发挥前后两级EFP的侵彻能力,改善了串联装药的侵彻效果。To solve the problem of fast perforating hunk tralse to tne reqmreo aepLu auu WLUL,, dem shaped charge structure was proposed by using two same structures of explosively formed projectile （EFP） charge. The forming process of the new structure was simulated and the effect of the interval distance on the forming process of tandem EFP charge analyzed by using finite element software LSDY- NA3D. On this basis, an experiment for tandem EFP penetrating steel target was conducted. The results show that the tandem EFP charge can make full use of the penetrating capability of the two shaped charges and improve the penetration effect.
