| 摘 要： | 运用自行研制的二维流体动力学程序TDY2D,对一点起爆半球壳装药装置中散心爆轰波的传播过程进行数值模拟计算.对冲击波到达炸药和飞层各界面的波形的计算值与实验值进行了对比,两者符合较好,从而验证了该程序的准确性和有效性;对爆轰波的传播过程进行了分析研究,获得了一些散心爆轰波传播的规律性认识,为进一步研究散心爆轰波特性提供了数值分析基础.

| Abstract: | The TDY2D code is developed to simulate the propagation of divergent detonation waves in a hemispherical explosive shell initiated at centered point.The data of the relative running times of the detonation wave along the surfaces of the explosive and of the flyer computed by using TDY2D are in good agreement with the experimental records.The propagation characteristics of the detonation wave are analyzed and some useful conclusions are reached. |
