Compound faults diagnosis and analysis for a wind turbine gearbox via a novel vibration model and empirical wavelet transform

Renewable Energy, 2019
Fault diagnosis of a wind turbine gearbox can schedule maintenance strategy on a wind turbine and save operational cost for wind farms. Owing to low rotational speed and weak vibration energy, fault diagnosis for planetary stage is arduous in a wind ...

SEACKgram: a targeted method of optimal demodulation-band selection for compound faults diagnosis of rolling bearing

Structural Health Monitoring
Rolling bearing plays an important role in carrying and transmitting power in rotating machinery, and the bearing fault is easy to lead to mechanical accidents, resulting in huge losses and casualties. Therefore, the condition monitoring and diagnosis of

A three-dimensional geometric features-based SCA algorithm for compound faults diagnosis

Measurement: Journal of the International Measurement Confederation, 2019
To achieve compound faults diagnosis with single channel signal, a three-dimensional geometric features-based sparse component analysis (TGF-SCA) method is proposed.

Compound faults diagnosis based on customized balanced multiwavelets and adaptive maximum correlated kurtosis deconvolution

Measurement: Journal of the International Measurement Confederation, 2019
Due to the compound faults with different type fault coupled together and the nonobvious periodic impulses contaminated by strong noise, it is challenging to extract the fault characteristics from the rotating machinery.
