摘要
介绍了谐波小波分析及其滤波方法 ,并运用该方法对转子系统振动信号进行分析 ,提取信号特征 ,识别转子临界转速。实践表明 。
Harmonic wavelet analysis and its filter method is introdaced.We use this method to analyze the vibration signals of a rotor system,to abstract the features of the signals and identify the critical speed of the rotor.Practice shows that this method and its results are practically valuable.
