基于复合面/背板的平板装药防护性能

摘要

The protection performance and mechanism of explosive reactive armors (ERA) with composite rubber armor as its front or back plate were investigated using experiments and numerical simulation,and the results were examined in comparison with ERA using conventional steel plates of the same area density.The experimental results show that the protection performance of ERA with composite rubber armor as the front or back plates are superior to that of the ERA with steel plates,and the optimal performance is achieved when the rubber composite armor is used as the back plate.The numerical simulation results show that the back plate velocity of the composite rubber armor is 16％ higher than that of the ERA with steel plates,the space between the two moving plates of the composite rubber armor and the boundary effect contribute significantly to reducing the length of the escaping shaped charge jet.%采用实验和数值模拟方法研究了橡胶复合板作为爆炸反应装甲面、背板时的防护性能,分析了两种反应装甲结构的防护机理,并与面密度相同的钢反应装甲进行了对比.实验结果表明:爆炸反应装甲面板或背板为橡胶复合板时的防护性能优于钢反应装甲,其中橡胶复合板作为背板时效果最优.数值模拟结果表明:橡胶复合板在爆炸驱动下外层钢板速度相比于钢反应装甲飞板提高16％,橡胶复合板的界面效应及其飞板间隙可以有效减小逃逸射流的长度.
