Abstract :
When gearbox operated abnormally, a frequency vibration energy of signal after undecimated wavelet transformation would have great changes, the online monitoring and diagnosis system of wind turbine gearbox was developed accordingly. Measured the vibration signal of bearing fault in the laboratory, The results showed that this proposed method can be more accurate display characteristics, which was conducive to diagnose bearing failure quickly and effectively.
