| 摘 要： | 风机噪声属于空气动力性噪声，但这种观点一直缺乏严密、科学的理论根据。本文从振动、谱分析及相关理论等角度，全面、系统地分析了风机所有的噪声源，识别出主要噪声源确为空气动力性噪声，并为减振、降噪提供了理论和实验基础。

| Abstract: | Blower noises belong to the aerodynamic noise. The paper completely and systematically analyzes all of the noise sources about a centrifugal blower from angles of vibration, spectrum analysis and cohernt theory, assures that the major source of the noise is indeed the aerodynamic noise, and provides theoretical and experimental basis for reduction of vibration and noise. |

| Keywords: | centrifugal blowers noise modal response pulse |
