| 摘 要： | 针对同一成型装药形成多模毁伤元问题,利用LS-DYNA 程序,研究了单点起爆位置对爆炸成型
侵彻体(explosivelyformedpenetrator,EFP)成型的影响规律。当起爆点距离药型罩的轴向距离从0倍装药
口径增加到0.72倍装药口径,EFP速度提高了37.8%,长径比增加了1倍多;优化设计成型装药结构,分析
了主装药端面中心点起爆和药型罩顶点起爆爆轰波传播规律,实现了杆式EFP、EFP2种模态的转换。通过
X光成像实验进行了验证,实验结果与数值模拟结果吻合较好。

| Abstract: | Aimed at forming multimode penetrators with the same shaped charge,the LS-DYNA software was used to explore the effects of the point initiation position on the formation of an explosively formed penetrator(EFP).When the axis distance between the liner and the initiation point increased from 0 to 0.72 times as long as the charge caliber,the EFP velocity increased 37.8 percent and the length-diameter ratio increased over 100 percent.The charge shape was optimized.The diffusion of the detonation waves was anal... |
