摘　　要：应用一维应变流体弹塑性波分析半穿甲弹高速碰撞薄装甲靶板的冲击波传播、炸药装药对冲击波的动态响应 ,以及激发炸药碰靶早炸的准则 ,建立碰炸临界靶板厚度和临界碰撞速度的计算模型。In this paper the elastic plastic wave theory of one dimensional strain fluid is used to analyze the propagation of the shock wave,the dynamic response of the charge to the shock wave,and the condition of the charge prematurity during the SAP impacts to target plates in the high velocity.Based on this analysis,the calculating model of the critical thickness of the target plates and the critical impacting velocity is constructed.An example is given to check the accuracy of the model.

关 键 词：半穿甲弹 早炸 临界厚度 临界速度
