摘　　要：分析了船舶液压设备噪声控制的必要性,介绍了船舶液压设备噪声污染的特点、危害,并阐述了船舶液压设备噪声几种评价量及如何获得其噪声级和控制船舶液压设备噪声的3种基本方法,并重点从设计选型、优化装配、隔震、阻尼及吸声等方面提出了降低船舶液压设备机械和流体噪声源的方法和措施,为船舶液压系统的噪声控制及降噪设计提供了参考。This paper analyzes the necessity of noise control for the marine hydraulic system,introduces the characteristic and harm of the noise pollution,and elaborates several evaluation values of noise and how to acquire the noise level.And then three basic approaches to control noise are put forward.Methods and measures of reducing mechanical and fluid noise source in the marine hydraulic system are presented in the fields of design and type-selection,optimal assembly,shock insulation,damp,sound absorption,and so on.So this paper provides a reference to noise control and noise reduction for the marine hydraulic system.
