| 摘 要： | 利用APX-RS数字式高速相机拍摄了PETN炸药水下爆炸气泡自由场脉动过程、气泡与边界相互作用水射流形成过程的清晰图像。采用氙灯照明光源,高速相机幅频可以达到6000s-1,采用在水箱壁贴低密度材料的方法来降低反射冲击波对气泡脉动过程的影响,由高速相机测试结果分析得到的气泡脉动参数与8kg爆炸水池试验结果一致,验证了光学测试结果的真实性。

| Abstract: | The explicit pictures of bubble oscillation at free field and water jet formed during bubble and boundary interaction at underwater explosion was captured by APX-RS digital high-speed camera with the frame rate of camera of 6000 s-1 by using Xe lamp. The wall of the water tank was equipped with a layer of acoustic-impedance materials,and the bubble oscillation was not influenced by shock waves reflected from the wall of water tank. The experimental data obtained by high speed camera agree with the experimental results of 8 kg test pound. |
