摘要
本文采用LagrangeAutodyn 2D程序 ,计算仿真实际尺寸的一代爆炸反应装甲盒 (REA)在起爆后各飞板的运动规律以及相互作用的特点。仿真和实验结果表明上下飞板和面板的速度相一致 ,上飞板与面板碰撞后将断裂 ,在上飞板和下飞板之间有一空间可使主级装药射流无干扰通过 ,串联战斗部具有较小的延时时间 ,最佳的着靶姿态和较小的干扰因素。
Numerical simulation for the velocity histories and moving features of plates in a typical explosive reactive armor of practical size was carried out following the Autodyn 2D code. The experimental and simulation results show that the plate velocities at different times are precisely determinated. Particularities of the velocity histories allow the tandem shaped charge warhead to posses a shorter time delay and to defeat the main armor in a better attacking status. The experimental measurements have approved the demonstrations of the numerical simulations.
