Dynamic Characteristics of Externally Pressurized Rectangular Porous Gas Thrust Bearings

Abstract

A theoretical study on the behavior of an externally pressurized rectangular porous thrust bearing is made using compressible lubricant. A periodic load is imposed on the bearing and the pressure distribution which leads to the determination of stiffness and damping is obtained by small perturbations. The results are calculated numerically using a digital computer. The tabulated theoretical data of a square pad given for a wide range of design variables enable one to use directly in the design. A design procedure of such a bearing is also indicated.
