Abstract Performance of air foil thrust bearings is strongly influenced by the stiffness characteristics of the foil structure. In this paper, a fully coupled elasto-gasdynamic model for air foil thrust bearings is presented. Top and bump foil are modeled as two-dimensional thick shells including shear, membrane, and bending effects.

Abstract The selection of a thrust bearing for the operational reliability of turbomachinery is very important because it supports axial loads and influences the lateral vibration caused by the thrust collar tilt. A type of integrated hybrid air foil-magnetic thrust bearing (i-HFMTB) is hereby proposed to overcome the limitations of the ...

Static and Dynamic Characteristics of Air Foil Thrust Bearing Considering Tilting Pad Condition
Volume 5: Turbo Expo 2007, 2007The thrust pad of the rotor is used to sustain the axial force generated due to the pressure difference between the compressor and turbine sides of turbomachinery such as the gas turbines and turbochargers. Furthermore, this thrust pad has a role to maintain and determines the attitude of the rotor.

Thermo-aerodynamic analysis of herringbone groove air foil thrust bearing
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering TribologyThis article presents a three-dimensional(3D)thermoaerodynamic(TAD) model for Herringbone grooved air foil thrust bearings (HG-AFTBs). The analysis is performed by solving the non-isothermal Reynolds equation and the 3D energy equation with temperature-dependent viscosity and density.

Model Validation for Air Foil Thrust Bearings
This work validates and extends a simulation model for an air foil thrust bearing, which belong to the class of hydrodynamic bearings with elastic bearing surfaces. The model can determine integral quantities such as load-carrying capacity and power loss of the bearing.openaire +1 more source
Analysis and Optimization of Single-Pad and Multi-Pad Air Foil Thrust Bearings
Air foil bearings are a type of compliant hydrodynamic bearing that feature a reliable, low-maintenance, and ecological machine element for high-speed turbomachinery. Due to the utilization of surrounding air or other gases as a lubricant, they can be used in oil-free machines.openaire +1 more source
