摘要
本文针对某高层楼供水系统管道振动大、噪声污染严重的问题,应用有限元与试验模态分析相结合的方法,对输液管道进行模态分析,求得其固有频率和模态振型,为供水系统减振降噪研究提供了可靠依据。
To solve the vibration and noise problem ofthe pipe system in water supply in high building, by usingfinite element analysis and experimental modal analysistechnology, the modal analysis of the pipe system inwater supply is made. The nature frequency and modalmode is obtained, and the result provides credibleinformation for the research of vibration and noisereduction of the water system.
