摘要
研究分析了一种新型的聚能罩结构——星锥罩结构射流形成的特点,即射流发生了二次碰撞,产生了二次射流。并采用有限元软件LS-DYNA中的多物质ALE算法,成功地实现了星锥罩射流形成过程的三维模拟。计算结果表明:星锥罩形成了高速的二次射流,运用多物质ALE法对星锥聚能装药结构进行模拟是可行有效的。
To make a study of a new style shaped charge liner configuration-star liner,the character of the jet forming is got. The secondary jet collision happens to produce secondary jet. Using the multi-material arbitrary Lagrangian-Eulerian(ALE) method in LS-DYNA, the 3D simulation of the jet forming is successfully realized. The result shows: the secondary jet with high speed is got. It is available to simulate the shaped charge configuration using ALE.
