Non-linear identification of a squeeze-film damper [PDF]
Described is an experimental study to identify the damping laws associated with a squeeze-film vibration damper. This is achieved by using a non-linear filtering algorithm to process displacement responses of the damper ring to synchronous excitation and

An Analytical Turbulence Model for Squeeze Film Damper Short-Bearing Analysis
Applied MechanicsThis paper develops an analytical turbulence model for open-ended squeeze film damper (SFD) application. Prandtl’s mixing length theory is adopted to describe the momentum transfer within the damper for its thin-film turbulent flow.

Dual clearance squeeze film damper for high load conditions [PDF]
Squeeze film dampers are widely used to control vibrations in aircraft turbine engines and other rotating machinery. However, if shaft unbalance rises appreciably above the design value (e.g., due to a turbine blade loss), a conventional squeeze film ...

The Stability of the Steady State and Bistable Response of a Flexible Rotor Supported on Squeeze Film Dampers [PDF]
, 1991 The stability of the steady state response, the bistable response, and the jumping characteristics are analyzed for the case when a system accelerates or decelerates through the bistable region of a flexible rotor-centralized squeeze film damper system ...
