摘　　要：为了在大块度障碍物上快速开孔且孔深和孔径符合要求,提出了一种前后两级均为爆炸成形弹丸(EFP)装药的新型串联聚能装药结构。分析了装药结构参数对串联EFP侵彻威力的影响,并在此基础上分别开展了串联EFP装药在不同装药间距与起爆延时条件下侵彻45钢靶实验。实验表明,优化后的串联EFP装药结构使前后两级EFP装药的侵彻效率大大提高,能对硬目标进行有效破孔。To realize that hunk fraises can be fast perforated and the perforated depth and width are enough,a new tandem shaped charge structure was proposed by using two same structures of explosively-formed projectile（EFP） shaped charges.And the effects of the structural parameters on the tandem EFP charge penetration power were analyzed.Based on the above analysis,experiments were conducted for tandem EFPs penetrating 45 steel targets under different charge spacings and different initiation delays,respectively.The results show that the tandem EFP charge structure can greatly improve the penetration efficiency of the two-stage tandem shaped charge and it can be used to effectively penetrate hard objects.
