摘要
预制破片战斗部是导弹中较常用的战斗部之一。研究其爆炸冲击波的特性,可为破片战斗部的设计与毁伤效应研究提供参考。鉴于目前还很难给出多层预制破片战斗部爆炸波的精确解析表达式或经验公式,本文运用动力有限元分析软件LS-DYNA,仿真模拟了一层和两层预制破片战斗部爆炸波的超压与比冲量。仿真模拟分析表明,一层预制破片战斗部仿真模拟结果与经验公式能够较好吻合;而两层预制破片战斗部的仿真模拟结果在适当修正经验公式后,两者才能够较好吻合。
Pre - fragmented warhead is used commonly in missiles. It can give references for the design and damage effects research of fragmentation warhead to study the characteristics of the explosive shock wave. Because it is difficult to deduce a precise analytical expression or empirical formula for explosive wave of multi - layer Pre - frag- mented warhead, the author simulated the explosive shock wave of one and two - layer Pre - fragmented warhead by using the kinetic finite element analysis software LS - DYNA. The results show that the simulation of one - layer Pre - fragmented warhead tallies with the empirical formula, and the simulation of two - layer Pre - fragmented warhead can tally with the amended empirical formula, too.
