复合药型罩EFP的形成及数值模拟

设计了两种可形成复合EFP的复合药型罩装药结构,即内层等壁厚、外层变壁厚以及内层变壁厚、外层等壁厚的复合药型罩。通过数值模拟及破甲毁伤实验,对复合EFP的形成和透靶毁伤效果进行了研究。结果表明,两种装药结构都可以形成复合EFP。与内层等壁厚、外层变壁厚组成的复合药型罩相比,内层变壁厚、外层等壁厚形成的药型罩效果更好,其后效毁伤区域更大。与单层EFP相比,复合药型罩形成的EFP对目标的毁伤后效效果更好。

EFP Forming and Numerical Simulation for Double Layered Charge Liners

Two charges of double layered charge liner, with the same thickness of inner,the variety of the outer layer and the variety of inner, the same thickness of the outer layer of double layered charge liners,were designed which can form complex EFP.The forming of complex EFP and the damage effect of penetrating target were studied by numerical simulation and experiment. The results indicate that the two charge structures can form complex EFP. The EFP forming effect of the latter is better than the former, and the second damage volume of the latter is larger than the former.The formed EFP of double layered charge liner has better damage effect than the single EFP.
