TL;DR: A review of proper orthogonal decomposition (POD) methods for order reduction in a variety of research areas is presented in this paper, where the historical development and basic mathematical formulation of the POD method are introduced.
Journal ArticleDOI
Influencing factors of the dynamic hysteresis in varying compliance vibrations of a ball bearing
TL;DR: In this paper, the hysteretic characteristics of the varying compliance (VC) principal resonance in a ball bearing were investigated by using Floquet theory, and the resonant response displays a swallow-tail structure due to the coupling nonlinearities between the Hertzian contact and the bearing clearance.
Journal ArticleDOI
The Varying Compliance Resonance in a Ball Bearing Rotor System Affected by Different Ball Numbers and Rotor Eccentricities
Journal ArticleDOI
Periodic response analysis of a misaligned rotor system by harmonic balance method with alternating frequency/time domain technique
TL;DR: In this article, a dynamic model is established for an offset-disc rotor system with a mechanical gear coupling, which takes into consideration the nonlinear restoring force of rotor support and the effect of coupling misalignment.
Journal ArticleDOI
Analysis of vibration signals for a ball bearing-rotor system with raceway local defects and rotor eccentricity
TL;DR: In this paper, a symmetrical rigid bearing-rotor system running in flexible bearing supports was modeled and the influence of the resonance characteristics and rotor eccentric excitation on the fault characteristic frequencies was analyzed via envelope analysis performing on the dynamic response from the numerical simulation at different speeds.
