摘　　要：用相干功率谱分析法辨识在多振源工况下的主要噪声源，并对被识别声源作自功率谱和倒功率谱分析，诊断出产生噪声的故障元件。This paper employed the coherent power spectrum to distinguish the Source of main noise under the condition of several vibration sources,and made a spectrum and cepstrum analysis for the noise source which has been distinguished,the failure components coueing the noise were diagnosed.

关 键 词：相干功率谱 噪声控制 倒功率谱 噪声源
