Abstract/Summary:
In the present thesis, the numerical analysis of Brown was applied to a number of cases involving hydrostatic and hydrodynamic lubrication. Then, for the first time it was applied to pure hydrostatic lubrication. The influences of various parameters such as spring stiffness, spring arrangement, flow rate, pad thickness and load on the convergence were explored. For the converged solution, specific information was developed for the influence of viscosity, spring arrangement, size of the central lubricant supply pocket and the load on the lubricant film thickness.;The present author designed and supervised the assembly/fabrication of a test facility for a spring-supported thrust bearing pad under hydrostatic lubrication conditions. The test facility included loading frame, hydrostatic bearing, oil supply system and instrumentation. Some of the components were fabricated in-house while others were "out-sourced". Extensive component fabrication drawings were developed using (AutoCAD and SolidWorks software) and listed in the Appendices of the present thesis. (Abstract shortened by UMI.)...
