小波变换在轴承故障诊断中的应用

Diagnosis of Bearing Fault Using Wavelet Transform

提出一种利用连续小波变换诊断轴承故障的方法。该方法不需要对象的数学模型，具有灵敏度高、仰操能力强、鲁棒性好的特点。

A diagnosis approach has been presented for bearing fault using continuous wavelet transform(CWT).No model is needed for the monitored objects in this method,which is sensitive to faults and robust to noise.
