摘要
针对高层楼供水系统管道振动大、噪声污染严重的问题,应用有限元法,建立供水系统管道的有限元模型,并进行管道的模态分析,求得了固有频率和模态振型,为供水系统减振降噪及改造提供依据。
Aimed at the vibration and noise problem of the pipe system of water supply,by the means of finite element method,the model of the pipe system is built.Modal analysis is made and the nature frequency and modal shape are calculated.The result provides a reliable foundation for reducing vibration,lowering noise level and system rebuilding.
