船舶水下噪声研究三十年的基本进展及若干前沿基础问题

Some progresses of underwater noise of ships in the recent thirty years and several new basic problems

三十年来,船舶水下噪声研究取得了显著的进展,同时也面临新的需求和挑战。文章从船体结构振动和声辐射、低噪声设备、管路系统振动和噪声、隔振及声振隔离方法、声学材料和元器件、推进器及推进轴系声学特性、水动力噪声、声呐自噪声、声目标强度、声学测量方法等十个方面,简要回顾和梳理了船舶水下噪声研究取得的主要进展及进一步的发展方向,并提出了若干前沿的基础性问题。

In the recent thirty years, some significant progress has been made in the field of underwater noise for ships, meanwhile new demands and challenges are facing now. This paper briefly reviews and sorts out the main progress achievement as well as directions developing in the future, which includes vibration and acous-tic radiation of ship structure, low noise equipments, vibration and noise of pipe systems, vibration isolation and acoustical vibration isolation, acoustic materials and components, acoustic design of propeller and propul-sion shafting, hydrodynamic noise, sonar self-noise, acoustic target strength, acoustic measurements, and so on. Above all, several new basic problems are also put forward.
