水深对毁伤效应的影响实验研究

Experimental research on influence of depth on damage effect

对于浅水中耐压舱体结构的毁伤效应人们开展了相关研究,由于深水环境中(50~300 m)静水压力的存在,处在其中的耐压舱体承受一定的预压力,预压力的存在对耐压舱体在聚能装药作用下的毁伤效应产生的影响尚不明确。该文设计单次使用模拟深水爆炸实验装置,开展不同模拟水深条件下耐压舱体结构在聚能装药作用下的毁伤效应研究。研究结果表明:在0~3 MPa静水压力条件下,水深对耐压舱体靶板的破坏、水中冲击波压力峰值以及耐压舱体前板中心位移无明显影响,对于耐压舱体结构,浅水中的研究结果可以应用于深水环境中。

The research on damage effect of pressure-proof cabin structure in shallow water had been carried out,due to the presence of hydrostatic pressure in deep water environment(50-300 m),the pressure-proof cabin in which it is subjected to a certain pre pressure,the effect of pre pressure in the damage effect of pressure-proof cabin under the action of shaped charge is not clear.An experimental equipment for simulating deep water explosion was designed,and damage effect research of pressure-proof cabin affected by shaped charge under different simulated depth was conducted.The research shows that depth has no appreciable influence on failure of pressure-proof cabins,shock peak or displacement of the front plate center of the pressure-proof cabin under 0-3 MPa hydraulic pressure.The results in low depth can be extended to the cases of deep water for the pressure-proof cabin in this research.
