电爆炸箔驱动飞片运动影响因素的实验研究
(1) U-T与I-T曲线表明, Cu爆炸箔在充电电压为2800V时，能量利用率最高，桥区尺寸为0.2mm×0.2mm的箔桥比桥区尺寸为0.3mm×0.3mm的爆发功率和爆发电流略大。
(2) PDV测试时得到飞片速度的原始频率数据，经过软件处理得到速度图像。充电电压为2800V时，桥区尺寸为0.2mm×0.2mm的Cu爆炸箔所得飞片速度比桥区尺寸为0.3mm×0.3mm的略大。

Title Experimental study of factors on flyer drived by electrical explosion foil
Abstract
In the dissertation, the parameters of exploding foils, flyer and barrel in the exploding foil initiator were designed. Utilized the closed-field unbalanced magnetron sputtering iron plating system to coat, applied pico-second laser micromachining system to carve bridge shapes, and manufactured the exploding foils of Cu. And the electrical explosion performance of exploding foils were determined by testing system of high-voltage pulse power source existed. The flyer velocity of exploding foil initiator was measured by photonic Doppler velocimeter (PDV). The main research results were as follows:
(1)The U-T and I-T curves suggest that when Cu exploding foils are at 2800V charging voltage, the energy utilization efficiency is the highest. When Cu exploding foils are at 2800V charging voltage, the exploding currents and power of Cu exploding foils at 0.2mm×0.2mm bridge area are slightly larger than that at 0.3mm×0.3mm bridge area.
(2) Raw frequency data of the flyer velocity was measured by photonic Doppler velocimeter (PDV),and the velocity images obtained by software. When Cu exploding foils are at 2800V charging voltage, the flyer velocity of Cu exploding foils at 0.2mm×0.2mm bridge area are slightly larger than that at 0.3mm×0.3mm bridge area.
