Abstract
Based on the methods of wavelet analysis, taking the gearbox CA6140 as a subject investigated, this paper introduces the application of wavelet analysis and wavelet envelope spectrum in fault diagnosis field. Though Daubchies wavelet decomposition and Hilbert envelope spectrum analysis, the failure frequency of the vibration signal of the gearbox can be found out.
