Published Online: September 24, 2009
...Tsuyoshi Inoue; Yasuhiko Sugawara; Motoki Sugiyama Active magnetic bearing (AMB) becomes widely used in various kinds of rotating machinery. However, as the magnetic force is nonlinear, nonlinear phenomena may occur when the rotating speed becomes high and delays of electric current or magnetic...

A Time-Varying Stiffness Rotor Active Magnetic Bearings Under Combined Resonance

U. H. Hegazy, M. H. Eissa, Y. A. Amer
Journal: Journal of Applied Mechanics
Publisher: ASME
Article Type: Research Papers
J. Appl. Mech. January 2008, 75(1): 011011.
https://doi.org/10.1115/1.2755118
Published Online: January 14, 2008
...U. H. Hegazy; M. H. Eissa; Y. A. Amer This paper is concerned with the nonlinear oscillations and dynamic behavior of a rigid disk-rotor supported by active magnetic bearings (AMB), without gyroscopic effects. The nonlinear equations of motion are derived considering a periodically time-varying...
