本文采用Lagrange Autodyn-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。
Abstract
Numerical simulation for the velocity histories and moving features of plates in a typical explo?sive 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 demonstra?tions of the numerical simulations.
