摘要
针对高层供水管道系统产生的噪声污染问题进行了系统的理论分析和实验研究。分析了管道系统的振动激励源及管道系统的动态特性 ;并根据管道系统动态特性、振动和噪声信号特点等 ,分析了实例中管道系统噪声产生的原因 ,采取了相应的改造措施 。
Sound radiation from the piping structures of the water supply system for high buildings poses was analysed.The vibration excitations of piping systems was investigated.The example was given to demonstrate the testing procedure. Based on dynamic behavior of piping system and the characteristics of vibration and noise signal, the noise resource has been found out, and associated measures are adopted to reduce the noise. The results show the proposed method is effective.
