RISStructural and Rotordynamic Force Coefficients of a Shimmed Bump Foil Bearing: An Assessment of a Simple Engineering Practice
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High speed rotors supported on bumptype foil bearings (BFBs) often suffer from large subsynchronous whirl motions. Mechanically preloading BFBs through shimming is a common, low cost practice that shows improvements in ...
