摘　　要：为了深入研究火药燃速在不同条件下的规律,采用密闭爆发器实验和分段数据拟合函数法,通过DY630和SF-3两种火药的燃速压力指数和燃速系数变化规律来分析燃速的变化规律,并与经典理论进行对比分析。分析表明,多孔粒状药的燃速压力指数比单孔管状药的燃速压力指数要小:实际燃速的u-P曲线中的直线阶段(主燃烧阶段)为经典理论的u-p曲线。In order to study the gunpowder burning rate kw under different conditions,the variation of DY630 and SF-3 two gunpowder burning rate pressure index kw and burning rate coefficient was analyzed by closed bomb experiments and segmented data fitting function,and the gunpowder burning rate kw was compared with that of the Classical Theory.Results show that the burning rate pressure exponent of Porous granular Propcllant is smaller than that of the hole tubular Propellant;The linear stage(the main combustion phase) in die u—p curve of the actual burning rate was the u—p curve of me Classical Theory.
