本文对破甲射流与爆炸装甲相互作用的机理进行了研究。建立了射流受爆炸装甲覆盖板的断续干扰和连续干扰的力学模型;推导了运动薄板受射流作用的扩孔公式;提出了射流干扰度的概念;并与实验进行了对比。 In this paper, the mechanism of the interaction between armor jet and explosive armor is studied. The mechanical model of intermittent interference and continuous disturbance of jetted armored cover is established. The reaming formula of the motion plate subjected to jet action is deduced. The concept of jet interference is proposed. The experimental results are also compared with those of experiments.
