Fault diagnosis of planetary gearbox based on acoustic signals
The reliability of planetary gearbox is extremely important for safe and reliable operation. In
this work, a fault diagnosis method based on acoustic signals is proposed for planetary
gearbox, where the generated acoustic signals are nonlinear and non-stationary. First, the
Fourier decomposition method (FDM) is utilized to decompose the measured acoustic
signals into Fourier intrinsic band functions (FIBFs). Compared with the traditional empirical
mode decomposition (EMD) method, FDM has better decomposition effect results without …
