Amplitudes of characteristic frequencies for fault diagnosis of planetary gearbox
TL;DR: In this paper, the amplitudes of characteristic frequencies based on a phenomenological model were explored for a planetary gearbox and a modified sideband energy ratio (SER) was proposed to deal with the problem of rotating speed fluctuation.
Journal ArticleDOI
A phase angle based diagnostic scheme to planetary gear faults diagnostics under non-stationary operational conditions
TL;DR: In this paper, phase angle data extracted from measured planetary gearbox vibrations is used for fault detection under non-stationary operational conditions, together with sample entropy, and the proposed scheme proves to be effective and features advantages on fault diagnosis of planetary gearboxes under nonstationary operating conditions.
Journal ArticleDOI
Weighted domain adaptation networks for machinery fault diagnosis
TL;DR: A multiple source domain adaptation method is proposed to learn fault-discriminative but working-condition-invariant features from raw vibration signals, based on their distributional similarities to the target working condition.
Journal ArticleDOI
An ameliorated synchroextracting transform based on upgraded local instantaneous frequency approximation
TL;DR: The synchroextracted operator in SET is upgraded in terms of second-order Taylor expansion to estimate the fast and strong frequency modulated signals so that a better TFR can be achieved.
Journal ArticleDOI
Motion periods of sun gear dynamic fault meshing positions in planetary gear systems
TL;DR: A systematic scheme to explore the motion periods of the sun gear fault meshing positions in a planetary gearbox, namely tidal periods is proposed, which is proved to be a minimized time duration that embrace complete fault induced information.
