摘　　要：分析了反应装甲与射流作用的机理,应用瞬时爆轰相关理论,建立了飞板运动方程,在此基础上建立了反应装甲飞板转角工程计算模型,利用该模型得到了飞板任意微元、任意时刻的转角参数.研究结果表明飞板在运动中转角只与其速度和炸药的爆轰速度有关,与数值计算和实验的结果相吻合.利用流固耦合方法分析了夹层装药对飞板的作用,为研究平板与射流的相互作用过程提供了飞板变形的相关数据.The interaction principle of reactive armor and jet was discussed. By the theory of instantaneous detonation, the motion equation of flying-plate was built, and rotation angle model of flying-plate was founded. The rotation angle parameter of any cell of flying-plate at any time was obtained by the model. The results show that the rotation angle of flying-plate cell merely relates to the cell velocity and detonation velocity of explosive. The result of calculation coincides with that of experiment. The effect of sandwich charge on flying-plate was analyzed by coupling fluid and solid. The study offers reference for studying interaction between flying-plate and jet.
