Abstract

This paper presents the analysis of a non-recessed worn hybrid journal bearing with orifice restrictors. Using Newton-Raphson method, FEM is used for solving Reynolds equation governing the flow of lubricant in the bearing clearance space. The bearing performance characteristics are presented for a wide range of wear depth. The results are computed for an orifice-compensated hole-entry configuration with uniform distribution of holes in the circumferential direction. The results show that the wear affects the bearing performance significantly and therefore, a due consideration of wear defect should be given for an accurate prediction of the bearing performance over a number of cycles.
