| 摘 要： | 在一维流体动力学程序中，使用了JWLT状态方程，对强爆轰驱动飞片的实验模型进行了数值模拟研究，得到了炸药爆轰产物的压力和密度分布，验证了强爆轰的存在，同时得到了二级飞片自由面的速度曲线，与实验测量结果符合较好，为解释实验结果和设计新的强爆轰实验提供了计算依据，同时验证了程序的正确性。

| Abstract: | The concept, application back ground and generation of strong detonation were briefly introduced. The JWLT equation of state was embeded in one dimensional hydrodynamic program. The experimental model of strong detonation was simulated with the program. The pressure and density distribution of production of explosive were drew, and the existence of strong detonation was shown. The velocity curves of second flyer free surface are in good agreement with the experimental results. This work may afford validation and reference for studying the strong detonation. |
