摘要： 为了解决在大块度障碍物上快速开孔且孔深和孔径优化匹配的难题，提出一种前后两级均为爆炸成型弹丸（EFP）装药的新型串联聚能装药结构。利用有限元软件，分析隔爆结构对串联EFP装药侵彻能力的影响为了解决在大块度障碍物上快速开孔且孔深和孔径优化匹配的难题，提出一种前后两级均为爆炸成型弹丸（EFP）装药的新型串联聚能装药结构。利用有限元软件，分析隔爆结构对串联EFP装药侵彻能力的影响进行相应的串联EFP装药侵彻45_#钢靶实验。实验结果表明:隔爆体形状对串联EFP后级装药侵彻能力有重大影响，优化后的串联EFP后级装药整体侵彻深度和后级侵彻深度分别提高了23%和35%，大大改善了串联EFP后级装药的利用效率。

Abstract: In order to solve the optimal matching issue of penetrating hole depth and aperture on fast perforating into a hunk obstacle, a new tandem shaped charge structure is proposed, which uses two same structures of explosively formed projectile (EFP) shaped charge. The effect of explosion-proof structure on the penetration ability of tandem EFP charge is analyzed by using finite element software, and the associated experiment of tandem EFP penetrating into a steel target is conducted. The results show that the shape of explosion-proof body has an important effect on the penetration ability of postpositive charge of tandem EFP, and the whole penetration depth of optimized tandem EFP and the penetration depth of postpositive charge are increased by 23% and 35%, respectively, greatly improving the efficiency of postpositive EFP charge.

Key words: ordnance science and technology, tandem explosively formed projectile, explosion-proof body, structure design, experimental study, numerical simulation
