摘　　要：文中采用非线性动力分析软件LS-DYNA,应用ALE算法,对中心式动能杆战斗部动能杆在爆炸载荷作用下的驱动过程和动能杆之间的复杂碰撞飞散过程进行了数值模拟,对比研究了动能杆战斗部中填充低密度泡沫时对动能杆的空间分布特性的影响。Employing ALE arithmetic, the process of KE rod deployed by explosive and it＇s disperse characteristic were simulated with the non-linear and dynamic finite program of LS-DYNA. The influence on the disperse characteristic of rod was discussed when adding low density foam around rods.
