EFFECT OF FLUID INERTIA ON SQUEEZE-FILM DAMPER FORCES FOR SMALL-AMPLITUDE CIRCULAR-CENTERED MOTIONS. Conference Paper uri icon

abstract

  • Fluid-film forces generated by squeeze-film dampers (SFD) in response to small-amplitude centered motions are of special interest for stability analyses of rotating machinery employing SFDs with strong centering springs. They form the basis for calculation of linearized damping and inertia force coefficients obtained by subjecting the journal center to very small perturbations in velocity and acceleration. The analysis considers the fluid flow in an open-ends SFD due to small-amplitude circular-centered motions.
