摘　　要：基于圆筒装药结构的格尼模型及爆轰产物的γ律状态方程,提出了一种通过炸药密度及爆速估算其格尼系数的方法。用该方法估算了一些炸药的格尼系数,并与实验值进行了对比。结果表明,估算值与实验值的偏差较小,该方法能够满足工程应用的需要。A method to estimate the Gurney coefficient of explosive via the density and detonation velocity of explosive was proposed based on the Gurney model of cylindrical configuration and polytropic equation of state for detonation product.The Gurney coefficient of some explosives was estimated by this method.The calculated values were compared with the measured values.The results show that the deviation of the estimated values with the experimental ones is small and this method can meet the needs of the engineering applications.
