动力与传动装置的振动经支承基座传递至船体,是引起船舶振动与辐射噪声的重要因素之一,也直接影响了船舶声学性能与海洋声学环境。本文阐述了船舶动力与传动装置振动控制技术理论研究及工程应用的基本背景,从动力学优化设计、振源控制、被动控制、主动控制等方面梳理了国内外动力与传动装置振动控制技术的发展现状;着重从面向功率流控制的低频主被动隔振、自适应系统与宽频带振动控制、基于超材料/超结构的振动噪声控制、面向声辐射的振动智能感知与控制等角度凝练了相关振动控制技术的发展趋势。结合我国动力与传动装置振动控制技术面临的应用挑战提出了发展建议:加强动力与传动装置振动基础理论研究,加快关键技术攻关与转化应用;鼓励开发系列化振动主动控制装置产品,建立完善的行业技术标准体系;强化国家级研究平台以及人才培养基地,加快推进“产学研”深度融合。

The vibration waves induced by marine power and gearing systems travel to the hull structure through various supporting bases,which is one of the important factors that cause ship vibration and underwater sound radiation and also directly affects the acoustic performance of ships and ocean acoustic environment.First,a comprehensive review on the theoretical research and engineering application of the vibration control technologies for marine power and gearing systems is presented,and the state of the art of the vibration control technologies is introduced from the perspectives of dynamic optimal design,vibration source control,passive and active control.Next,the technologies that need to be developed,such as the low-frequency active/passive vibration isolation for power flow control,adaptive system and broadband vibration control,metamaterial/metastructure-based vibration and noise control,and intelligent vibration sensing and control for sound radiation,are proposed.The challenges of vibration control technologies for marine power and gearing systems are analyzed subsequently,and countermeasures are further proposed.To promote the vibration control technologies for marine power and gearing systems in China,research on the vibration control theories need to be strengthened and the research and application of key technologies needs to be accelerated.Furthermore,the development of various active vibration control devices and the related technical standards system should be encouraged and established.National research platforms and talent training bases should be consolidated and the integration of industry,research institutes,universities and customers should be promoted.
