摘要
用双灵敏度激光干涉测速技术测量了充电电压为18 kV的电炮加载下薄膜飞片自由面的速度历史。介绍了相关的实验装置及测量方法,给出了实验结果,并讨论了影响测速的一些关键技术。整个测速过程约为1.6μs,最终速度为6.7 km/s。
Free surface velocity histories of a film flyer driven by electrical gun at charging voltage of 18 kV were measured using bi-sensitivity VISAR. The experimental setup, testing method, and experimental results are given in this paper. Several key factors for velocity measurement are discussed. The whole testing process lasted 1.6 μs, and the final velocity reached at 6.7 km/s.
