Thrust bearing lubrication involves fluid-thermal-structural interactions between the oil film, the pad and the collar. Conventional solutions simultaneously solve the Reynolds, energy, film thickness, viscosity-temperature, solid heat conduction and solid deformation equations with many assumptions and simplifications. This study used the 3D fluid-structure interaction technique to investigate the thermal-elastic-dynamic lubrication in a small thrust bearing for a steady-state operation without those assumptions. Pressure, temperature, thickness distributions of the oil film and the heat transfer coefficients on the pad are analyzed. The results show that this technique combining CFD and FEM models can accurately model thrust bearing lubrication problem and explain the lubrication mechanism better.
