摘要
从离心式通风机生产的空气动力噪声、结构噪声及电机的电磁噪声的机理出发 ,对风机的噪声与振动特性进行了测试分析 ,提出了影响风机噪声与振动特性的关键因素 ,为低噪声离心式通风机的设计提供了必要的试验依据。
This paper studied the mechanism of different noise that produced from centrifugal blower,such as aerodynamic noise,structure noise and electromagnetic noise from motor.Tested and analyzed the noise and vibrating characteristics,and the key factor that influence it.Provided the necessary references to design low noise centrifugal blower.
