复合装药结构隔板实验与数值模拟

摘要

为得到钝感炸药(IHE)和高能炸药(HE)复合装药结构对冲击波感度的响应情况,对不同结构的复合装药进行隔板实验,得到了其冲击波感度与药柱高度比值的一阶指数关系.利用显式有限元程序对复合装药结构进行隔板实验的数值模拟,计算结果与实验结果吻合.通过数值模拟计算并比较了铝、有机玻璃、钢隔板和未反应JB-9014炸药的爆轰反应边界值.%The influence of composite charge of insensitive high explosive (IHE) and high explosive (HE) on the shock sensitivity was investigated through the gap tests of different explosive charge structures. It is shown that there is first order exponential relationship between shock sensitivity and height ratio. The gap test of composite charge was simulated using an explicit finite element program. The simulating results are identical with the data obtained from the experiment. The detonation reaction boundary values of Al, plexiglass, steel and unreacted JB-9014 explosive were obtained and compared.
