The novelty of this paper is to numerically investigate the effect manufacturing error and misalignment on transient lubrication behavior dynamically loaded journal bearings with micro-groove. Based average Reynolds equation considering mass conservation cavitation algorithm, asperity contact model, force balance equation, mixed model under time-varying dynamic loads developed. Meanwhile, mathe...

The modeling of tilting-pad journal and thrust bearings presents a level complexity beyond that with fixed-arc geometry, particularly regard to their dynamic influences. With bearings, the theory surrounding fluid film must be complemented representative pad dynamics. What has been recognized in recent decades is significance support, particular flexibility pivot region pad. typical model for i...

The lubrication performance of journal bearings with different sorts of uniformly distributed micro-spherical textures are studied in this paper. Geometries and dynamic models of journal bearings with pure concave/convex textures are developed. The validity of the proposed models is verified against the oil film pressure distribution from the literature. The effects of geometry parameters (the ...
