Abstract

Abstract

The radiation noise of mechanical noise have a significant impact on the acoustic detection performance of acoustic detection underwater gliders, in order to address this problem, this paper introduces absorber into the study of radiation noise of underwater gliders. Firstly, the theoretical models of different absorbers are established in this paper, and according to the theory of microperforated panel absorber and porous material absorber, the composite absorber for reducing the radiation noise of underwater glider is proposed, and the simulation analysis of the composite absorbers are carried out by using COMOSL software for guiding the design of the composite absorber. The results show that the composite absorber of porous sound material-air cavity-microperforated panel-parallel air cavity has the best performance in the range of 0-2000 Hz, its absorption coefficient is 0.662 in the range of 200-1200 Hz, which can reduce the radiation noise of the underwater gliders under specific working conditions and improve the acoustic detection ability of underwater gliders.
