摘　　要：研究炸药爆轰驱动与加速金属能力的表征与评定方法,为炸药的选型与应用等提供理论和技术支撑。基于瞬时定容爆轰和产物等熵膨胀假定,分别采用多方指数型状态方程和JWL状态方程推导了爆轰驱动与加速金属的驱动压力模型和驱动能量模型;采用所得到的模型对6种典型炸药进行了计算,并分析了驱动压力和驱动能量随爆轰产物膨胀进程的变化规律;在此基础上,提出了表征与评定炸药爆轰驱动与加速金属能力的参数——驱动压力指数(Kp)和驱动能量指数(KE)。研究结果针对炸药爆轰驱动与加速金属的能力提供了定量表征与评定方法,为炸药爆轰性能和驱动与加速金属能力的关联性给出了理论依据。The characterization and evaluation methods of explosive detonation driving and accelerating metal capability are studied. Based on the assumption of instantaneous constant volume detonation and the product of the entropy expansion, the driving pressure model and the driving energy model of detonation driving and accelerating metal were derived by using the multi exponential and JWL state equation respectively. Then 6 typical explosives were calculated by the model, and the variations of the driving force and the driving energy with the expansion process of detonation products were analyzed. And the parameters driving pressure index ( K p ) and the driving energy index ( K E ) were proposed to characterize and evaluate the detonation driving and metal acceleration. The results were provided a quantitative characterization and evaluation method,and given theory evidence about the relationship between explosive detonation performance and the ability to drive and accelerate metal.
