| 摘 要： | 为研究点起爆发散爆轰波驱动飞片的运动特性，自行研制了二维流体动力学程序TDY2D，采用由实验所标定炸药的状态方程参数，对3种长径比相差较大的点起爆炸药驱动平板飞片运动的模型进行了数值模拟计算，并对结果进行了分析。计算所得的飞片运动历史和击靶波形均与实验符合较好，具有较高的计算精度，从而验证了该程序的准确性和有效性。

| Abstract: | In order to study the characteristics of flyer's acceleration by divergent detonation wave,a 2D numerical code TDY2D was developed.By using the equation of state of detonation products which are got by computing for the experimental models,the TDY2D is used to compute the motion of flyers driven by slab charge that initiated at centered point for three experimental models which are three kinds of explosive-flyer assemblies with different length/diameter ratio.The simulation results about the velocity of som... |
