摘要
实验研究了脉冲氙灯在高负载条件下掺铈石英玻璃管壁的特性,并对实验结果进行了分析。在氙灯的输入能量为爆炸能量的60%的高负载条件下进行实验,随着运行发次的增加,氙灯的电极出现龟裂;氙灯灯管内壁出现白色花纹、块状乳白色积淀物和丝状裂纹;石英玻璃释放出的氧气使管内气体的高频火花放电颜色由紫蓝色变为绿色。放电过程中,灯管主要受冲击波和热负载两方面的作用。通过对冲击波和热负载对灯管作用机理和实验结果的对比分析得出,热负载是氙灯灯管内壁出现圆环形丝状裂纹等现象的主要原因,冲击波会加速灯管的破裂。
Abstract
The characteristic of pulse xenon flashlamp envelope, which made of cerium doped quartz glass, was studied experimentally under high input power, and the experimental results were analysed. The experimentation was performed under the condition that the input energy of flashlamp is sixty percent of the explosion energy. With the number of shot increasing, map cracking occurs at the surface of the electrode, and white pattern,milky white deposition and hairline cracks emerge on the inner surface wall of the envelope. The oxygen released from the quartz glass envelope changes the color of the gas under high frequency spark discharge from indigo into green. Shock wave and thermal load are the two main effects on the envelope during the discharge. The analyse results indicate that thermal load is the major reason for hairline crack occured in the inner wall of envelope and shock wave will accelarete cracking of envelope.
