摘要

摘要: 为获得实验条件对水下爆炸实验结果的影响，实验研究了测点位置、实验深度与冲击波峰值压力、比冲击波能、气泡脉动周期、比气泡能之间的关系。结果表明：冲击波峰值压力和比冲击波能随测点与爆心距离的增加而降低；炸药的实验深度越深，气泡脉动周期越小，比气泡能越大。测点与爆心的距离应至少大于两倍的气泡半径，炸药的实验深度应为水池深度的1/3～3/4。

Abstract: In order to obtain information about the influence of experimental conditions on the results of underwater explosion, the relationships between measure position, explosion depth and explosion parameters, which contain shock overpressure, shock wave energy per unit mass, bubble pulsation period and bubble energy per mass, were studied by experiments. The results show that the peak pressure of shock wave and shock wave energy per unit mass decrease with the increment of distance between measuring position and explosive sample, the bubble pulsation period increases and bubble energy per mass decreases with the increasing of the explosion depth. The distance between the measuring position and explosion position are at least greater than twice of the bubble radius, and the explosion depth should be 1/3 to 3/4 of the tank depth.
