Squeeze Film Characteristics In Flat Hydrostatic Bearings with Incompressible Flow

This paper is concerned with squeeze film damping in hydrostatic pads having the various types of compensation normally used (i.e., capillary, orifice and constant-flow). A computerized analysis is used to determine bearing squeeze film pad performance with the various compensation types. A parametric study is made on the single-recess rectangular pad with a wide range of pad geometry considered. Each pad geometry is combined with each of the compensation types for the complete range of static pressure ratios. A sample problem is presented which demonstrates the use of hydrostatic squeeze film characteristics and design curves developed. Presented at the 24th ASLE Annual Meeting in Philadelphia, May 5–9, 1969.
