hence highly nonstationary. Conventional spectral analysis and demodulation analysis methods are unable to identify the … characteristic frequency of gear fault from such nonstationary signals. As such, this paper presents a time–frequency analysis … methods to reveal the constituent frequency components of nonstationary signals and their time-varying features for WT …
