50%爆炸的隔板厚度是表示炸药冲击波感度的一种简单比较方法。本文提出一个简便的测量装置,能准确地测量冲击波在不同材料隔板中的行进距离随时间的变化关系,从而计算隔板中不同厚度处的冲击波速度和冲击波压力。实验研究给出了Ly-12铝、45号钢和有机玻璃隔板的结果,以及它们之间的相互比较。
The 50% exploded separator thickness is a simple comparison of explosives shock sensitivity. This paper presents a simple measuring device that can accurately measure the shock wave propagation distance in different material separators with time, so as to calculate the shock wave velocity and shock wave pressure at different thickness in the separator. Experimental studies have given the results of Ly-12 aluminum, 45 steel and plexiglass separator, and their mutual comparison.
