| 摘 要： | 爆轰冲击波动力学（Detonation Shock Dynamics，DSD）是目前研究爆轰波非理想传播的有效途径。利用DSD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-30 ℃下直径为10～30 mm药柱的直径效应实验数据，利用遗传算法确定了低温下JB-9014钝感炸药的DSD参数。由DSD参数计算得到了JB-9014药柱中的定态波形和爆速，计算结果与实验结果符合。

| Abstract: | Detonation shock dynamics(DSD) method is an effective way to study the non-ideal propagation of detonation waves.Using the generalized geometrical optics model of DSD,the non-ideal propagation of detonation waves is studied for explosive grain with high slenderness ratio.A computer code is developed to calibrate the DSD parameters for JB-9014 insensitive high explosive by genetic algorithm.Calibration data are obtained from measurements of the detonation velocities and detonation wave fronts in JB-9014 explosive at low temperature of-30 ℃,with diameters of 10-30 mm.The steady-state detonation velocities and detonation wave fronts predicted by these DSD parameters can fit the experimental data within the experimental uncertainty. |
