高层楼供水管道系统的实验模态分析

EXPERIMENTAL MODAL ANALYSYS OF THE PIPE OF WATER SYSTEM IN HIGH BUILDINGS

针对高层楼管道供水系统振动较大 ,环境噪声污染严重的问题 ,采用现代试验模态技术对供水管道系统进行模态分析 ,得出了管道系统的模态参数 ,为高层楼供水系统减振降噪研究提供了可靠的依据 .

To solve the vibration and noise problem of the pipe structure in water system in high building, the modal analysis of water system is made by using modern experimental modal analysis technology.The nature frequencies and modal parameters are obtained ,and the result provides credible information for the research of vibration and noise reduction of the water system.
