摘要
利用理论公式和数值模拟方法计算出12种不同方案下药型罩为大锥角型的EFP速度,应用灰色系统理论对所考虑的因素进行分析,建立了各个因素与EFP速度之间的灰关联度矩阵。通过对灰关联度矩阵的分析,得到了影响EFP速度的主要因素依次为装药密度、炸药爆轰速度、药型罩锥角、药型罩直径、装药高度和药型罩壁厚,对EFP的药型罩设计和装药结构设计具有重要参考价值。
The theortical analysis and numerical simulation of the of EFP velocity were conducted which is formed by the big-cone shaped line in this paper, and twelve schemes of the EFP velocity are be considered by the theory formula and numerical simulation. The influence factors of EFP velocity are be analysis by the grey system theory, and the grey correlation matrix has been established between all the kinds of influence factors with the EFP velocity. The primary influence factors on the velocity of EFP is follow by the density of explosive, the angle of line, the velocity of detonate, the diameter of line, the height of explosive and the thickness of explosive though analysis the grey correlation matrix, and offered a referenced evidence on the design of lines and explosive structure.
