爆破战斗部水中兵器爆炸威力评定方法研究

Research on Evaluation Method of Underwater Blast Brisance of Weapon's Explosive

为确定爆破战斗部水中兵器爆炸威力评定方法,正确反映水中兵器作战性能和毁伤目标能力,基于某舰船缩比模型的海上爆炸试验,以标准TNT药球作为爆源,根据试验实测的冲击波压力数据和气泡脉动数据,分析对比目前爆破战斗部水中兵器爆炸威力评价的常用方法,即冲击波压力峰值推算法和战斗部爆炸相对能量评估方法,计算装药的TNT当量。结果表明:战斗部爆炸相对能量评估方法具有更高精度,可作为爆破战斗部水中兵器爆炸威力评定的通用方法。

In order to determine the evaluation method of weapon＇s explosive power and to reflect the underwater weapons operational performance and damage to the target properly, based on a ship scale model, the standard TNT explosive was tested as explosion source in this study. According to the experiment data, the shock wave pressure and gas bubble pulsation were analyzed and compared, including the commonly used explosive power evaluate methods such as shock wave pressure peak prediction and warhead evaluation method of relative explosive energy to calculate explosive TNT equivalent. As a result, the evaluation method of relative explosive energy has higher precision and it can be used as a general method for evaluation of weapon explosive power.
