Abstract

The present paper deals with the theoretical study of geometric imperfections of journal and its influence on the performance of capillary-compensated six-pocket hybrid journal bearing configurations with different geometric shapes of recess. The analysis includes the geometric imperfections of journal such as barrel shape, bellmouth shape, and circumferential undulations and various geometric shapes of recess (square, circular, elliptical, triangular) of same pocket area. The governing Reynolds equation is solved using Galerkin’s technique. The numerically simulated results indicate that the selection of suitable geometric shape of recess is important to have the least influence of different geometric imperfections of journal on the bearing performance.
