| 摘 要： | 采用连续小波分析的方法对滚动轴承振动和速度信号进行处理，提取滚动轴承故障特征。通过对滚轴承在正常、内圈剥落、外圈剥落及滚动体落情况下的振动加速度信号进行分析，验证了这种方法的有效性。

| Abstract: | A method using CWT(continuous wavelet transform) is proposed to analyze vibration signal of rolling element bearings. Vibration signal of rolling element bearings with inner ring pitting, outer ring pitting, rolling pitting and no default are analyzed. The result shows the validity of CWT in fault diagnosis of rolling element bearings. |
