摘　　要：管路系统振动和噪声是影响舰船声隐身特性的主要原因之一。本文根据舰船管路系统的布置特点,分析了舰船管路系统中主要的振动和噪声源。论述了泵、阀门和管内两相流在管路系统中引起的各种振动和噪声的特点以及它们的产生机理,并依据管路系统振动和噪声的产生特点,给出了相应的解决思路,为舰船振动和噪声的治理以及管路系统减振降噪提供了理论基础,为指导舰船管路系统减振降噪工作的开展提供了依据。Noise and vibration of naval piping system is one of key points which inference the character of acoustic stealth of naval.The mainly sources of noise and vibration were analysis based on the lay of naval piping system.It were analysis that the trait and the emergence mechanism of noise and vibration of pump,valve and the air-water two-phase flow in pipe,and then the corresponding solutions to control the noise and vibration of piping system were given,which could be used to reduce the noise and vibration of naval,and offer the theoretical methodology of vibration and noise control of naval piping system,and could be used to guide the expandedness of this work in the future
