RISPreliminary Experiments With Foil Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A capacitive probe, coincident with the surface of a revolving drum, scans the air gap between a flexible foil and the rotating cylinder. Preliminary measurements of foil displacement are made ...
An Experimental Study of High-Speed Rotors Supported by Air-Lubricated Foil Bearings—Part 2: Response to Impact and to Periodic Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-speed rotor, supported by an air-lubricated foil bearing is stable at speeds up to and in excess of 60,000 rpm. “Natural frequencies” are determined at various rotational speeds from ...
An Experimental Study of High-Speed Rotors Supported by Air-Lubricated Foil Bearings—Part 1: Rotation in Pressurized and Self-Acting Foil Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-speed rotor, supported by an air-lubricated foil bearing, is rotated in both the vertical and horizontal attitudes at speeds in excess of 60,000 rpm. The rotor is stable and free from ...
The Dynamic Characteristics of a Turborotor Simulator Supported on Gas-Lubricated Foil Bearings—Part 2: Operation With Heating and Thermal Gradients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-speed rotor, supported by gas-lubricated foil bearings, is free from self-excited whirl and displays no loss of load capacity when vibrated at frequency equal half the rotational speed ...
The Dynamic Characteristics of a Turborotor Simulator Supported on Gas-Lubricated Foil Bearings—Part 1: Response to Rotating Imbalance and Unidirectional Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 16-in-long rotor, weighing approximately 21 lb, was supported by air-lubricated foil bearings. In physical size and in mass distribution, the rotor was closely matched with that of an ...

The Dynamic Characteristics of a Turborotor Simulator Supported on Gas-Lubricated Foil Bearings—Part 3: Rotation in Foil Bearings of Reduced Length, With Starting and Stopping Unaided by External Pressurization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments and analysis, reported in detail in references [1] through [5], demonstrated that high-speed rotors, supported by foil bearings, were free from whirl-instability and sensitivity to ...

An Experimental Study of Elastohydrodynamic Lubrication of Foil Bearings: Part 1—Displacement in the Central Zone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elastic foil under tension is wrapped partly around a rotating cylinder and is supported on a thin film of air. Capacitance probes, coincident with the surface of the cylinder, scan the ...
