摘要
本文概述船舶噪声的定义、来源、造成的影响以及降低船舶噪声所采用的技术方法,介绍国内外船舶噪声控制技术的研究现状,从主动控制技术、被动控制技术、主被动混合控制技术3个方面论述船舶降噪技术。重点介绍了表面涂层技术对于降低船舶噪声的应用,分析了阻尼涂层的降噪机理及降噪性能,最后阐述几种对于船舶降噪技术具有应用前景的新型材料以及未来船舶降噪技术的发展趋势。
In this paper,the definition,source,impact,and method of noise reduction are described.Domestic and foreign ship noise control technology was introduced.The ship noise reduction technology was introduced from three aspects:active control technology,passive control technology and active-passive hybrid control technology.The application of surface coating technology to reduce ship noise was highlighted,the noise reduction mechanism and noise reduction performance of the damping coating were analyzed.Finally,several new materials with application prospects for ship noise reduction technology and the development trend of future ship noise reduction technology are introduced.
