Abstract
The radiation noise of mechanical noise has a significant impact on the acoustic detection performance of acoustic detection-based underwater gliders.In order to address this problem,this paper introduced sound absorption structure into the study of radiation noise of underwater gliders.Firstly,the theoretical models of different sound absorption structures were established,and according to the sound absorption theories of microperforated panel and porous materials,the composite sound absorption structure for reducing the radiation noise of underwater gliders was proposed,and the simulation analysis of the composite sound absorption structure was carried out by using Comsol software for guiding the design of the composite sound absorption structure.The simulation results show that the composite sound absorption structure of porous material layer-air cavity-microperforated panel-parallel air cavity has the best performance in the range of 0-2 000 Hz,and its average sound absorption coefficient is 0.663 in the range of 200-1 200 Hz,which can reduce the radiation noise of the underwater gliders under specific working conditions,weaken the interference of self-noise,and improve the detection ability of acoustic detection-based gliders.关键词
