摘要： 设备不同部件振动机理不同，其激励源识别方法有所区别。针对旋转机械设备，利用试验手段，结合信号处理方法，研究时域、频域分析、自相关、互相关、包络分析等振源识别方法在实际设备中的工程应用，掌握不同激励源的识别方法。

Abstract: Different component parts of equipment have different vibration causes, so the methods of their vibration source identifications are also different. Based on the measurement data and the signal processing, some methods of vibration source identification, including time-domain analysis, frequency domain analysis, self-correlation, cross-correlation, envelope analysis etc., of rotational machinery and their engineering applications were studied. This work provides a help for handling different methods of vibration source identification.

Key words: vibration and wave, mechanical vibration, vibration source identification, signal processing
