摘要
本文采用平均平滑周期留法对水电机组机械振动信号进行了频谱分析,并通过细化分析的方法使系统频率分辨率的设置具有一定的灵活性。
The spectrums of the mechanical vibration signals on hydroelectric sets are analysed using a verage-smoothing-periodogram method, and the setting up of the frequency-resolving capability is made fexible by detailed analysis,and the errors are studied.
