摘要
以转镜式高速分幅相机作为记录载体,设计并建立了高速阴影系统。用该摄影系统研究在爆轰加载下金属表面的微喷射现象,以及由此产生的波阵面发展过程。通过获取的阴影图像观察到了带有特定形状缺陷(矩形槽、盲孔)锡自由表面的微喷射演变过程,给出了微射流的形状,冲击波阵面以及喷射物头部的运动速度等物理信息。
Based on ultra high speed rotating mirror framing camera, a high speed shadow photography was designed and set up. Micro-jet and its wavefront was observed on the Tin free surface loaded explosive which existed a strip of rectangle groove and three small blind holes. The shape of jet,velocity of shock wavefront and ejecta head were obtained through shadow images.
