Dynamic and Static Characteristics of a Rocker-Pivot, Tilting-Pad Bearing with 50% and 60% Offsets. (2012-02-14)Static performance and rotordynamic coefficients are provided for a rocker-pivot, tilting-pad journal bearing with 50 and 60 percent offset pads in a load-between-pad configuration. The bearing uses leading-edge-groove ...

Experimental Performance of an Open Ends Squeeze Film Damper and a Sealed Ends Squeeze Film Damper (2017-04-07)High performance turbomachinery often experiences severe dynamic loads that produce large amplitude rotor motions. Well-engineered squeeze film dampers (SFDs) provide adequate damping to ameliorate rotor vibrations and to ...
