高速纹影技术在爆轰实验中的应用

APPLICATION OF THE HIGH-SPEED SCHLIEREN TECHNIQUE FOR DETONATION EXPERIMENTS

本文描述了简单纹影装置的原理及其特征。介绍了纹影仪与转镜式高速相机结合时应满足的条件,给出适用于爆轰实验的纹影仪光学系统。最后,应用简单纹影装置和高速纹影仪分别拍摄了雷管的爆炸过程,取得了较好的结果。

The principle and characteristics of the simple schlieren apparatus are described in this paper. The conditions needed for the joint of the schlieren instrument with the high-speed rotating mirror cameraare also introduced. A typical optical system of the high-speed schlieren instrument for detonation test is illustrated. Finally, with this instrument, the detonating process of electrical initiators is recorded very well.
