This article features an Air Foil Thrust Bearing (AFTB) simulation model including wear prediction for a foil thrust bearing with an annular top foil. The bearing consists of 6 bearing sectors with independent bump foils, but possesses a single annular top foil with an embossed height profile. The bearing is analyzed by a detailed single-sector model utilizing symmetry properties and a cyclic coupling of the components. The compressible Reynolds equation and the 3D energy equation are used to obtain fluid film pressure and temperature. The model further includes thermoelastic deformations of the runner disk, elastomechanic deformations of the top and bump foils, and a detailed thermodynamic model of the rotor. A direct comparison of simulated and experimental results shows that top foil wear has to be taken into account in order to match simulated to measured data. Therefore, a wear algorithm is derived and incorporated into the thermo-elasto-hydrodynamic simulation model. Furthermore, the manufactured real top foil topology is determined by measurements in order to obtain in-depth topology information which is also included in the computation model. Simulation results with the TEHD model including a detailed surface analysis alongside a wear prediction are confirmed by measurements carried out on a dedicated test rig.
