Unite Model Solving Method and Analysis for Liquid Film Sliding Bearings

In this paper, the unite model solving method for calculating performances of hydrodynamic, hydrostatic or hydrostatic dynamic bearing is presented completely. The method bases on common mechanism for the bearings system and can describe truthfully whole lubrication field for the bearing. The error in calculating flow rate may be eliminated. The analysis of performaces of oil starvation or overflow for journal bearing is accomplished. The calculating examples have shown that the given method is conforming to reality accurately and saving computing time.
