摘要
Abstract
To study the property of shielded composition B initiated by a ⌀30mm 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 in￣itiation thickness of shaped charge jet to shielded composition B was obtained, and the critical velocity of jet impacting initi￣ation 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 fu￣ture.关键词
