摘要:
为研究Φ30 mm装药的聚能射流对屏蔽B炸药的冲击起爆问题，采用非线性有限元LS-DYNA程序数值模拟了聚能射流形成、侵彻及冲击引爆屏蔽B炸药作用过程，得到了射流穿过50~75 mm不同厚度屏蔽钢板的速度、直径以及侵入炸药界面的射流能量值，得到引爆B炸药的临界屏蔽板厚度，计算获得该聚能射流临界起爆速度。最后通过试验对数值计算的B炸药起爆特性进行了验证，试验结果与计算符合较好。研究证明，Φ30 mm装药的聚能射流对屏蔽B炸药的临界引爆屏蔽板厚度为70 mm，可用于反导战斗部毁伤目标。
Abstract:
To study the property of shielded composition B initiated by a Φ30mm shaped charge jet, the numerical simulation for the process of shaped charge jet formation, penetrating and shock initiating the shielded composition B was studied by means of nonlinear finite element analysis software LS-DYNA．The parameters, such as jet velocity, diameter and impact energy through the different shield steel plates in the thickness of 50-75mm were obtained. Also, the critical initiation thickness of shaped charge jet to shielded composition B was obtained, and the critical velocity of jet impacting initiation shielded composition B was calculated. These calculation results were examined by a series of tests. It concludes that the calculation results are in agreement with the experimental ones, and the critical initiation thickness of shaped charge jet with a charge diameter of 30mm to shield composition B is 70mm, which could be applied to anti-missile warhead in the future.
