爆炸深度对装药水下载荷的影响

Research on Influence of Depth of Charge on Underwater Explosion Load

进行了1 kg球形TNT裸装药水下爆炸试验和数值计算,研究爆炸深度对球形装药水下爆炸冲击波和气泡脉动的影响。研究结果表明:冲击波能随比例爆深的增加而小幅度下降,而气泡能和总能量与比例爆深不具有正线性关系,在h=75 m·kg^(-1/3)达到最大值。

Underwater explosion tests and numerical calculations were carried out on 1kg spherical TNT naked charges.The research results show that the shock wave energy decreases slightly with the increase of the proportional explosion depth,while the bubble energy and total energy do not have a linear relationship with the proportional explosion depth,and reach the maximum value at h=75/m·kg^(-1/3).In the design of underwater weapons,it is necessary to consider the impact of the explosion depth on the energy distribution of the warhead.
