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

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.
