- Abstract
As the key component of wind turbine, the gearbox is prone to failure due to the complexity of the operating environment and working conditions, which seriously threatens the safe and stable operation of the wind turbine. Therefore, the fault diagnosis of the gearbox is of great significance to ensure the stable operation of the wind turbine. On the basis of introducing the structural characteristics, failure modes and vibration monitoring of the gearbox, combined with the structural characteristics of the gearbox, the calculation method of the fault characteristic frequency of gears and bearings was given. At the same time, the combination of Hilbert transform and cepstrum analysis was used to analyze the vibration data of the gearbox, and the fault characteristic frequency was extracted. It is verified by an example that the method can be used to accurately obtain the fault frequency of the gearbox and locate the fault of the gearbox, so as to realize the fault diagnosis of the gearbox of the wind turbine.
