Title:Progress in modeling and experimental characterization of thrust foil bearings for oil free turbomachinery
Speaker:Daejong Kim / The University of Texas at Arlington
Abstract: Foil bearing is one of the air/gas-lubricated hydrodynamic (or aerodynamic) bearings that do not require an auxiliary oil lubrication system. The bearing surface is typically made of thin metallic foil and is supported by a compliant structure providing structural stiffness and damping to the bearing. The most popular compliant structure is a corrugated metal, the bump foil. Foil bearing is a widely used oil-free bearing technology along with active magnetic bearings. In contrast to the magnetic bearing, foil bearings work at extremely high temperatures, up to 650oC and cryogenic temperatures, if the lubricating gas media has proper viscosity.
In recent years, foil bearings have found use in many industrial applications where oil-free operation is advantageous, such as gas turbine generators, turbo blowers, and refrigeration compressors. The bearing load capacity is typically presented in terms of the specific load capacity (SLC), which is load capacity divided by the bearing projection area (shaft diameter times bearing length). Conventional foil bearings have sufficient SLC (100~200kPa) at high speeds and for intended applications. However, at low-speed operations such as startup and shutdown, the load capacity can be inadequate, especially for large-scale turbomachines, due to the heavy weight of the rotor. Hybridization with other load-supporting mechanisms is one way to improve the load capacity of the foil bearing. In hybrid foil bearing (HFB), externally pressurized air/gas is injected into the clearance of the bearing to levitate the shaft. The concept of hybridization has been applied to both radial and axial foil bearings.
This presentation provides recent progress in analytical models and experimental characterization of thrust foil bearings developed and tested at TESLAB including hybrid trust foil bearings.
