Research on Gearbox Composite Fault Diagnosis Based on Hilbert-Huang Transform
Jinying Huang · Coal Technology · 2010
A method to fault diagnosis of gearbox based on Hilbert-Huang transform was presented.Hilbert-Huang transform was used to the fault vibration signals of gearbox to get Hilbert energy spectrum.The composite fault can be identified by analyzing the spectrums.The experimental results show that Hilbert-Huang transform can effectively diagnosis composite fault of gearbox.
