本文对舰船管路系统常见几种管路元器件进行不同安装参数下振动传递进行试验研究，分析弹性支撑、挠性接管、直管段、弯管段等单独安装参数与集成安装参数对振动传递的影响。试验结果表明：安装参数可改变元器件刚度与阻尼，但对管路振动传递特性影响不大，刚度大的元器件对安装参数灵敏度较低。本文的试验结果可为舰船管路系统低噪声建造技术提供借鉴。
This paper analysis the influence of different installation parameters of some type ship pipeline elements upon vibration transfer, including flexible pipe, straight pipe, elastic pipe support and bend pipe. The experimental result show:pipeline installation parameters cloud change the stiffness and damping of the pipe elements, but have little influence on the vibration transfer. The pipe element with great stiffness is less sensitive to the installation parameters. The result of this paper can be used as reference for low noise construction of ship pipeline.
