摘　　要：为了提高爆炸箔起爆系统能量利用效率,采用仿真计算和试验相结合的方法,研究了不同铜箔厚度对爆炸箔起爆性能的影响规律。结果表明:当爆炸箔桥区尺寸为0.3mm×0.3mm时,铜箔厚度为3μm的爆炸箔电爆性能较好,能量利用率较高,在发火电压为1.5kV时,能量利用率达到72.33%,相对应的飞片速度最大。In order to improve the energy utilization ratio of the explosive foil initiation system,combining the simulation calculation and experiment research,the influence regularity of copper foil thickness on the initiation properties of explosive foil were studied.The explosion experimental results show that when the explosion foil bridge size is 0.3mm×0.3mm,the explosive foil with thickness of 3μm has the best electric detonation performance and the highest energy utilization.When the ignition voltage is 1.5 kV,the energy utilization rate reaches 72.33%,and the corresponding flyer velocity is the highest.
