基于小波分析的电机故障诊断研究

Study of the Electromotor Fault Diagnosis Based on Wavelet Analysis

详细地分析了电机的机械振动特性和小波多分辨分析原理。通过具体实验 ,表明了小波分析的良好时频局部化特性在电机机械故障诊断方面的有效性 ,并为其它机械故障诊断提供了有效的分析手段。

The mechanical characteristic of electromotor and the principle of wavelet multi resolution are studied.By means of material experiment,it shows that wavelet analysis with local feature well in the time frequency domain is very effective in mechanical fault diagnosis of electromotor,which can provide a valid analysis means for other mechanical fault diagnosis.
