摘　　要：为了提高用于模型试验的小型组合装药水下爆炸测试的可靠性和精确性,对由电雷管和扩爆药柱作为起爆元件共同起爆TNT药柱进行了水下爆炸测试,基于能量输出的等效原理,得到了起爆元件的TNT等效换算质量。结果表明:当主装药质量较小时,起爆元件对组合装药能量输出的影响十分明显,通过与炸药水下爆炸能量输出经验值的比较,验证了本文提出的等效换算方法的可靠性;就本文的试验工况而言,边界条件对于气泡最大膨胀半径的影响可以忽略不计,但随着装药整体质量的增大,一次气泡脉动周期的试验值与理论值的差距会显著增大。In order to increase the reliability and accuracy of underwater explosion（UNDEX） test of small-sized composite charges used in model experiment, the underwater explosion parameters of TNT grain initiated by the initiation component composed of electric detonator and auxiliary booster grain were measured. Based on the equivalent of energy output, the TNT equivalent quality of initiation component was obtained. The results indicated that the initiation component will greatly affect the whole energy out when the main charge mass is very small, and the equivalent conversion method is proved to be effective by comparing with the empirical values of the UNDEX energy output. In the existing experimental conditions, the effect of the boundary conditions on the maximum bubble radius can be ignored, while the difference between the experimental and theoretical pulsation cycle will be significantly enlarged.
