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.
