Published Online: February 21, 2022
... by a step-down engine torque, a new piecewise nonlinear clearance element with time-varying stiffness and oil squeeze damping is proposed, and an eight degrees-of-freedom (DOF) lumped parameters model with the new piecewise nonlinear clearance elements is established. The transient vibro-impact phenomena...

Nonlinear Oscillation of a Rotor-AMB System With Time Varying Stiffness and Multi-External Excitations

M. Kamel, H. S. Bauomy
Journal: Journal of Vibration and Acoustics
Publisher: ASME
Article Type: Research Papers
J. Vib. Acoust. June 2009, 131(3): 031009.
https://doi.org/10.1115/1.3085884
Published Online: April 22, 2009
...M. Kamel; H. S. Bauomy The rotor-active magnetic bearing system subjected to a periodically time-varying stiffness having quadratic and cubic nonlinearities is studied and solved. The multiple time scale technique is applied to solve the nonlinear differential equations governing the system up...
