Pressurized Oil Squeeze Film DampersSource: Journal of Tribology:;1980:;volume( 102 ):;issue: 001::page 41Author:A. Kent Stiffler

Abstract: A pressurized oil squeeze film damper supporting a rigid rotor mounted in antifriction bearings is investigated. Orifice and inherent feed inlets are examined, and it is shown that the clearance determines the inlet resistance for a groove or slot. The film stiffness and damping forces are determined as a function of the restrictor coefficient, rotor unbalance speed and the supply pressure using the short bearing approximation. These forces are related to the system transmissibility. A design methodology for low transmissibilities is presented.
