中文摘要：

针对希尔伯特变换与传统能量算子解调方法的缺点，提出一种新的解调方法——解析能量算子（AnalyticEnergyOperator，AEO）解调。仿真信号分析结果表明，相对于希尔伯特变换与传统能量算子解调，解析能量算子解调方法具有较高的解调精度。基于解析能量算子解调，又提出基于AEO能量谱的滚动轴承故障诊断方法，对滚动轴承仿真和实验信号进行分析，与其它方法的对比结果表明所提出方法的有效性和优越性。

英文摘要：

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.
