摘要: 为了解决测量管道内流体噪声的问题,我们尝试了附加测量水箱的测试方法。经分析,这种测量方法较好地解决了管道内的水噪声和压力波动分离的问题。通过试验验证,证实了这种测量装置及测量方法所测量的噪声能反映管道内水噪声的特性。

Abstract: A method for measurement of the fluid noise in pipe lines is proposed. The equipment for this method includes an additive small water tank. With this method, the water noise signal can be separated from the pressurenoise mixed signal in the pipe lines. The testing results show that the characteristics of the water noise in the pipe lines can be measured effectively with this method and this equipment.

Key words: vibration and wave, pipe lines, water noise, measurement
