散粒体炸药压装成型过程分析

Analysis of the Pressing Process of Several Granular Explosives

通过详细分析散粒体炸药压装成型物理过程的两个组成部分 ,提出了描述压装成型过程中密度随压力变化规律的指数方程ρs= 1- a1exp(- b1P) - a2 exp(- b2 P) ,该式在整个压力范围 (0～∞ )内精确度高 ,物理意义明确 ,适用于 JHL- 2、RT- 1、TNT、870 1和A- IX- 2等多种单质、混合、含铝炸药 。

In this paper, a exponential equation ρ s=1-a 1 exp (-b 1P)-a 2 exp (-b 2P) is presented, which can describe the rule of charge density varying with the compression pressure, though analyzing the whole pressing process of several granule explosives in detail. It is accurate in the whole range (from zero to infinite) of pressure. It can be applied to various granular explosives such as JHL 2?RT 1?TNT?8701和A IX 2 and so on. It is of practical value for engineering
