Dynamic Characteristics Of Fluid-Film Bearings
MetadataShow full item record
The concept of cross-coupling in bearings is introduced and its influence on bearing dynamics is presented. Procedures for obtaining cross-coupled spring and damping coefficients are explained. The special case of pad pitch coupling in tilting-pad bearings is discussed and the method, assumptions and equations made in reducing the complete tilting pad matrix to the more conventional 4 X 4 is presented. The closed form solutions for point mass bearing whirl utilizing the cross-coupled coefficients is developed in the discussion of bearing stability. Discussions of various bearing types with recommended geometric considerations are presented. Data on steady-state performance; cross-coupled coefficients and whirl stability of various bearing types are included.
