受试验场地条件限制,试验设计不得不采用多个几何缩比时,水下爆炸相似律将不再适用.本文从能量角度给出以水下爆炸动响应试验为目标的模型缩比设计换算律,能在一次试验过程中同时获取一次冲击波和气泡二次压力波冲击环境的测值.

Within the limits of experimental conditions,where the law of similarity with one and only geometrical scale for experiment of underwater explosion will not be suitable,several independent geometrical scales have to be selected in the experimental design.From the point of view of energy,this paper designed the scaling law between the prototype and the model to aim at the dynamic response experiment of underwater explosion.The measurements for two kinds of shock environments,i.e.,the first shock wave and the second pressure wave of bubble pulsing,can be obtained together.
