AEO解调方法及在滚动轴承故障诊断中的应用
Application of Analytic Energy Operator Demodulation Method to Fault Diagnosis of Rolling Bearings
摘要
Abstract
Aimed at the disadvantages of Hilbert transform and the conventional energy operator demodulation methods, a new demodulation method, analytic energy operator (AEO) demodulation method, is proposed. Compared to Hilbert transform and the conventional energy operator demodulation method, the AEO has higher demodulation precision. On the basis of AEO energy spectrum, a rolling bearing fault diagnosis method is put forward. This method is applied to analyze the simulated signals and actually tested signals of the rolling bearing. The comparison of the results with those of some other methods shows that the proposed method is of effectiveness and superiority.关键词
