| 摘 要： | 为研究金属桥箔电爆炸冲击波流场特征，根据冲击波运动自相似性，采用点爆炸模型描述了金属桥箔电爆炸冲击波的流场演化，建立了金属桥箔电爆炸后冲击波波阵面参数的理论计算方法. 给出了冲击波速度、压力、传播距离和粒子速度随时间的变化规律，将计算得到的冲击波传播距离和速度与实验结果进行了对比分析，计算结果与实验结果相符合.

| Abstract: | To study the characteristics of the shock wave flow field by metal bridge foil exploding, based on similitude theory of shock wave, a point explosion model was used to describe shock wave flow field evolution induced by metal bridge foil explosion. A theoretical calculation method for shock wave front parameters of metal bridge foil exploding was established. The velocity, pressure, propagation distance and particle velocity of shock wave front were obtained. The calculated velocity and propagation distance of shock wave are in good agreement with the previous experimental results. |
