摘要
The present work describes the static and dynamic performance of an orifice compensated hole-entry hybrid journal bearing system considering the combined influence of surface roughness and non-Newtonian behavior of the lubricant. The modified form of average Reynolds equation has been used for the solution of the lubricant flow field in the clearance space of a rough journal bearing system. The non-Newtonian lubricant has been assumed to obey the power law model. The effects of surface roughness parameter (Lambda), variance ratio ((V) over bar (rj)) and the surface orientations such as transverse, isotropic and longitudinal surface orientations on the performance characteristics of the bearing have been studied for various values of power law index (n).
