摘　　要：聚能装药形成的金属射流和 EFP是战争中对付坦克、装甲车辆等目标的技术手段 ,研究 EFP对炸药的引爆机理对于评估弹药受 EFP侵彻时的安全性具有非常重要的意义。通过计算 EFP侵彻带盖板装药时在盖板中产生的脱体冲击波压力 ,以及该压力在盖板与炸药界面处产生反射和透射作用后进入炸药内部的透射波压力强度 ,分析了 EFP破甲后冲击起爆炸药的可行性。Because the jet and EFP (Explosively Formed Penetrators) are mainly warheads to destroy the hard target (such as tanks, the armoured fighting vehicles, and etc.), it is very important to study the mechanism of EFP penetratings the explosive and initiating it for evaluating the stability of ammunition. In this paper, the pressure of the bow shock wave (BSW) which is produced when EFP penetrates the steel is calculated, then the pressure (of the refracted wave) in explosive is also calculated when the BSW crosses the interface between the steel and the explosvie. It is possible the refracted wave initiates the explosive when the FEP's velocity surpasses the critical velocity.
