摘要: 对二级炸药/飞片爆轰系统产生高速度飞片的需求背景作了介绍。在平面一维假定下，应用气体动力学的一维推体公式和推广的Gurney公式对次级飞片的速度进行了计算。在初级炸药和末级飞片厚度一定的条件下，对二级炸药/飞片爆轰系统的几何参数选取进行了优化分析，给出了爆轰系统驱动飞片的算例，与数值模拟结果和实验测量结果进行了比较，证实了经验公式的合理性。并对如何提高两级飞片的速度及平面度问题进行了探讨。Abstract: The driving abilities of strong detonation in two stages explosive/flyer system have been studied by both analysis and experiments. Under certain condition, the system's geometric parameters are optimized in order to drive final flyer to high speed. The abilities of strongly detonating explosive slab in driving metallic flyers to high speed are shown in our calculation model. Calculated results agree with experimental results. The performances of strong detonation are illustrated. And numerical calculation shows that converging detonation can be an effective method to accelerate a flyer up to high speed.
