为了分析水雾对舰船舱内爆炸冲击波的耗散与衰减作用,通过舱内装药爆炸试验研究方法,在有限空间爆炸舱中心设置爆源,测量并对比在有无喷雾工况下舱内典型位置的壁压和准静态压力。结果表明:在水雾抑爆的舱内爆炸试验中,水雾对舱内爆炸载荷的准静态压力和超压峰值削弱作用明显,其中27.5 g梯恩梯爆炸角隅位置的初始冲击波超压衰减率为26.47%,二次反射冲击波波峰值衰减率达到27.27%,准静态压力衰减率达到31.82%;喷雾液滴分布特性相同情况下,随着装药量增加,水雾对冲击波和准静态压力的衰减效果不断降低。 |

In order to analyze the mitigating effect of water mist on the explosive shock wave inside a cabin, a series of TNT explosion experiments in the center of a cabin were carried out, from which the wall pressure and quasi-static pressure inside the cabin in different cases with and without water mist were measured. Results show that water mist truly has an evident effect on attenuating the overpressure peak of blast wave and the quasi-static pressure. In the experiment of 27.5g TNT exploding in cabin, the attenuation rate of initial shock wave overpressure is 26.47%, the attenuation rate of secondary reflected wave pressure is is about 27.27%, and the attenuation rate of quasi-static pressure is about 31.82%. For the same water mist density, the mitigating effect of water mist on the blast wave decreases with the increase in TNT charge. |
