| 摘 要： | 提出了自组织包络解调（ＳＯＥＤ）算法，利用这个算法对轴承振动信号进行分析，不但可以从其时域信号中提取出纯净的周期性冲击，而且还能将信号的频谱准确地恢复到其特征频率处，因此在具体诊断时，只要检验其特征频率处的幅值大小，即可判断故障。

| Abstract: | The self organizing envelope demodulation method (SOED) is applied in order to analyze the vibration signal of rolling bearing. The periodic impulses can be demodulated from the original vibration signal while the characteristic frequency can be recovered. Hence the performance of a bearing can be evaluated by fixing the amplitudes on the characteristic frequencies. |
