形成尾翼爆炸成型弹丸的一种新方法

A New Method for Generation of Finned EFP

提出了形成尾翼爆炸成型弹丸的一种新方法,并用数值模拟手段验证了该方法。建立了数值计算模型,以正六边形罩 EFP 装药结构为例,展示了正多边形罩形成尾翼爆炸成型弹丸的过程。利用数值计算的结果分析了正多边形罩形成尾翼弹丸的机理。数值模拟结果及其分析表明:文中提出的方法可用于形成尾翼爆炸成型弹丸,且弹丸性能较优。

A new method for generation of finned EFP is brought forward and verified by numerical simulation. Numerical models are founded,and the model of the charge configuration with hexagonal liner is used as an example to illustrate the process that polygonal liner comes into finned EFP.The mechanism that polygonal liner forms finned EFP is analyzed by simulated results.The results and analyses indicate that the method put forward in this paper can be used to generate finned EFP.and the projectiles properties are...
