Routes to Chaos in Squeeze-Film Dampers
Design Engineering, 2004This work reports on a numerical study undertaken to investigate the imbalance response of a rigid rotor supported by squeeze-film dampers. Two types of damper configurations were considered, namely, dampers without centering springs, and eccentrically operated dampers with centering springs.

Application of Hydrostatic Squeeze-Film Dampers
A S L E Transactions, 1982Squeeze-film dampers are often used to improve the stability of high-speed rotating machinery. The introduction of a hydrostatic bearing as an additional damper support can further optimize the loading capacity and damping effects of the support system.

A Numerical Study of Squeeze Film Dampers
Volume 7B: Structures and Dynamics, 2013Squeeze film dampers (SFDs) are used in the high speed turbomachinery industry as a means to reduce vibration amplitude, provide damping, and improve dynamic stability of the rotor bearing system. Past numerical studies analyzing SFDs, have been computationally expensive and time consuming.

Equivalent Linearization of a Squeeze Film Damper
Journal of Vibration and Acoustics, 1986In this paper, the equivalent linearization of an intershaft squeeze film damper in a two shaft engine system is investigated. The two shaft centers at the damper position are assumed to move in different elliptical offset orbits and at synchronous frequency with the unbalanced rotor (e.g., the high pressure rotor).

Eccentric Operation of the Squeeze-Film Damper
Journal of Lubrication Technology, 1978The squeeze-film damper, undergoing a whirl orbit as may be caused by rotor unbalance, resists eccentricity of the whirl orbit with a static stiffness which is proportional to the dynamic force carried by the squeeze-film. In addition, the fluid film force would develop nonsynchronous components.
