摘要 爆轰冲击波动力学（DSD）是目前研究爆轰波非理想传播的有效途径。利用爆轰冲击波动力学的广义几何光学模型，研究了大长径比药柱中爆轰波非理想传播现象，根据常温下Ф10～Ф30mm药柱的直径效应实验数据，通过非线性优化方法——遗传算法，确定了一套JB-9014钝感炸药的DSD参数。这套DSD参数对JB-9014药柱中定态波形和爆速的计算与实验结果符合。 Detonation shock dynamics（DSD） is an approximation to the reactive Euler equations that allows numerically efficient tracking of curved detonation waves. The DSD parameters are the velocity- curvature relation and the boundary angle. A computer code was developed to facilitate the calibration of these parameters for JB-9014 insensitive high explosive using the generalized optics model of DSD. Calibration data were obtained from measurements of the detonation velocities and fronts in JB-9014 rate sticks at ambient temperature, with diameters of 10 -30 mm. The steady-state detonation velocities and fronts predicted by these DSD parameters are in very good agreement with experiment.
