Abstract: When a squeeze-film damper is operated eccentrically, the nonlinear damper forces are no longer radially symmetric and subharmonic and quasi-periodic vibrations may be excited by the rotor ...

Abstract: This paper investigates the unbalance response of a squeeze film damper-mounted flexible rotor, Both concentric and eccentric damper operations are examined. Comparison between predicted and ...

Abstract: The stability and bifurcation of the unbalance response of a squeeze film damper-mounted flexible rotor are investigated based on the assumption of an incompressible lubricant together with the ...
