Experimental Evaluation of Sector-Shaped Hydrodynamic Thrust Bearings Under Translation and Transverse Vibration

The bearing load of a plane inclined sector-shaped hydrodynamic thrust bearing, undersimultaneous translation and transverse vibration, is measured experimentally. The results are used to evaluate the lubrication theory solutions. Consequently, both the influences of the unsteady film inertia, measured by the squeeze Reynolds number Re s , and the convectiue film inertia, measured by the modified Reynolds number Re * , on load amplitude and phase are investigated
