In response to geopolitics, Taiwan's navy is in urgent need of strengthening its combat capability. As modern weapons technology continues to develop and change rapidly, the ability to resist underwater explosions must be considered to meet the combat needs of ships. Since the 1950s, European and American countries have conducted underwater shock tests on their combat ships to verify their weaknesses and seek improvements. In addition, by accumulating a large amount of actual ship explosion test data, an underwater detonation test database was established, and ship explosion and shock resistance design standards were formulated: such as MIL-901D, PD5500, BV0430/85 and other underwater shock spec-ifications. Taiwan's current academic research on underwater explosions still lags far behind that of Europe and the United States. First, the experimental facilities are backward. There are no large or medium-sized explosion pools and other experimental facilities in Taiwan, and the underwater explosion test capabilities are much behind those of advanced for-eign countries. In view of the huge cost of medium and large-scale underwater shock experiments, this paper focuses on micro underwater explosion. The experiments used micro-explosions, anti-underwater explosion water tanks, explosion pressure gauges and high-speed cameras to completely record the explosion pressure history of underwater micro-explo-sions, the formation and action process of bubble pulses. The experimental results clearly show that underwater explosions. During the process, the explosion pressure peak of the main shock wave and the subsequent bubble pulse phenomenon can be clearly seen. The experimental results can provide experimental data required for comparison and verification of underwater explosion simulation. |
