摘要
利用水下爆炸的光学可见,在浅水水体外将CCD高速摄像机实拍和图像处理技术引入了气泡脉动参数的测试研究,得到了0.3gDDNP装药的气泡半径随时间变化轨迹和脉动周期。为了验证测试结果的准确性,同时采用电测系统监测及经验公式计算,三种方法的结果非常一致。研究得出,随着装药入水深度增加,气泡脉动周期、最大半径都呈减小趋势,而气泡能变化不显著的结论。
The shoot of high speed video camera and the technology ot image manipulation are appned to test and study bubble pulsation parameters according to the optical visibility of underwater blasting. The track of bubble diameter changing with time and the pulsation period of 0.3g DDNP charge are obtained. To test the veracity of results, the monitor with electric measurement and calculation with experiential formula are carried out. Results from three methods are accordant. It is showed that the period of bubble pulsation and the maximum diameter incline to decrease with the deepness of water. Moreover, the change of bubble is not obvious.
