水下爆炸对沉底目标毁伤效应试验验证研究

Experimental Research on the Damage Effects of Bottom Torpedoes Shocked by Underwater Explosions

选择某沉底水雷为研究对象,对其在水下爆炸作用下的毁伤情况进行试验验证。首先对水雷在水下爆炸作用下的破坏模式进行分析,得到水雷在爆炸冲击作用下的失效方式;其次对水雷的毁伤机理进行分析,指出影响毁伤效果的几种决定要素。在此基础上采用试验方法对水雷在水下爆炸作用下的毁伤机理进行试验验证,通过自由场压力参数测量及雷体结构毁伤效果观测,对水下爆炸作用下水雷毁伤效果进行分析。根据试验结果,掌握不同爆距、不同方位情况下水雷毁伤规律特点,并给出其毁伤判据。

A sort of bottom torpedo has been selected as object and the damage effects of it that shocked by underwater explo⁃sion have been testified by experiment.Firstly,some damage models of torpedo have been ranked and the damage situations of the bottom torpedo have been given.Secondly,the damage mechanism of the torpedoes has been analyzed and the main factors of the damage effect have been put forward.Based on these,the damage mechanism has been validated by experiment method.The dam⁃age effects of bottom torpedo shocked by underwater explosion have been illuminated by free pressure measurement and the observa⁃tion of torpedo-structure damage effects.According to the experimental results,the damage characteristics of different explosion dis⁃tances and azimuth have been hold and the damage criterion of the bottom torpedo has been presented.
