串联EFP装药隔爆结构和延时起爆控制

结合串联战斗部的特点，提出了一种两级爆炸成型弹丸(explosively formed projectile, EFP)装药的串联装药结构。利用LS-DYNA有限元软件分析了不同隔爆体及延时起爆对后级EFP成型的影响，进行了不同隔爆结构和延时匹配的串联EFP侵彻45钢靶实验。实验结果表明:优化后的串联EFP装药的侵彻深度，已经达到分2次单级连续侵彻之和的96.7%，后级装药的侵彻能力得到有效提高。

Explosion-proof structures and delay detonation control of tandem explosively formed projectile charges

According to the analysis of the tandem warhead characteristics, we proposed a new tandem shaped charge structure composed of two explosively-formed projectile charges with the same structure.By using the finite element software LS-DYNA, the effect of different explosion-proof bodies and different delay control on the forming process of the postpositive EFP charge were analyzed.Based on the above results, we conducted experiments for tandem EFP penetration with different delay time.The experimental results show that the penetration depth of the optimized tandem EFP charge can reach 96.7 percent of the sum depth that penetrated by a single EFP charge at twice.The penetration ability of the postpositive EFP charge is greatly improved.
