Influence of Eccentricity and Angular Velocity on Force Effects on Rotor of Magnetorheological Damper [PDF]
EPJ Web of Conferences, 2018 This article presents the evaluation of force effects on squeeze film damper rotor. The rotor is placed eccentrically and its motion is translate-circular. The amplitude of rotor motion is smaller than its initial eccentricity.

Journal of Low Frequency Noise, Vibration and Active Control, 2021 Clearances between bearing outer ring and sleeve can generally be maintained to provide a margin for the thermal expansion of the bearings. However, temperature variation, improper assembly and long-term vibration can enlarge the clearances and ...
