A Thermohydrodynamic Solution of Pivoted Thrust Pads: Part II—Static Loading

Abstract

This is Part II, of a three-part sequence of papers on pivoted thrust pads. In this paper we apply the thermohydrodynamic theory of Part I to statically loaded, sector shaped pivoted thrust pads. The film shape is arbitrary and pad deformation can be specified once the geometry of the pad and the geometry of its support system are known. Presently we assume spherical crowning of the pad: crowning presents us with an opportunity to discuss film cavitation and its effects. Spherical-crowning is advantageous to employ, because it can be represented by a single parameter and because it yields the approximate shape of a loaded pivoted pad.
