Abstract

In order to study the impact of explosive performance on JPC molding, simulation software of AUTODYN-2D is used in JPC molding. Numerical simulation analysis of influences of five different explosives on JPC molding is performed. Method of determining the molding time is proposed. Two main results can be concluded. First, explosive material has no influence on JPC molding time. Under the same charge structure, JPC molding time of different explosive material has no difference. Second, the impact laws of explosive density and detonation velocity on JPC molding speed, fineness ratio and other molding parameters are proposed. The greater the density and detonation velocity of the explosive is, the better the performance of JPC molding parameters is and also the more conducive to the penetration of JPC, last verify the correctness and reliability of the laws by simulation test, the results provide a reference for rod shaped penetration warhead.
