Parameter Comparison Calculations for Oil Film Stability of Grooved Liquid-Lubricated Journal Bearing

Galerkin finite element method was used to evaluate the oil film stability of a spirally grooved liquid lubricated journal bearing.The correction interation method was used to determine the intersection of positive pressure region and cavitation region, on which the Reynolds pressure conditions were exactly satisfied.The comparative calculations of design parameters (spiral angle, groove depth, and groove width) were carried out to seek a parameter range corresponding to high oil film stability of the grooved journal bearing.
