An iterative solution technique has been developed for fluid film lubrication of large spring-supported thrust bearings subject to hydrodynarnic and hydrostatic lubrication using finite element analysis for pad deflection. Oil film pressures are obtained using a control volume formulation of me Reynolds equation while pad deflections are determined with a commercial finite element analysis package. Low rotor speeds are specified so that isothermal conditions prevail. A computer program links these two numerical methods to implement a solution procedure that consists of iterative loops for applied load, input flow rate, and pad deflection. Illustrative solutions have been obtained showing the influence of spring stiffness, lubricant viscosity, load, and location of the hydrostatic supply pocket.
