A Review of Tilting Pad Bearing Theory
International Journal of Rotating Machinery, 2011 A theoretical basis for static and dynamic operation of tilting pad journal bearings (TPJBs) has evolved over the last 50 years. Originally demonstrated by Lund using the pad assembly method and a classic Reynolds equation solution, the current state of ...

Evaluation of the Thermal Effects in Tilting Pad Bearing
International Journal of Rotating Machinery, 2013 The analysis of thermal effects is of expressive importance in the context of rotordynamics to evaluate the behavior of hydrodynamic bearings because these effects can influence their dynamic characteristics under specific operational conditions.

On the Instability Threshold of Journal Bearing Supported Rotors
International Journal of Rotating Machinery, 2014 Journal bearing supported rotors present two kinds of self-excited vibrations: oil-whirl and oil-whip. The first one is commonly masked by the rotor unbalance, hence being rarely associated with instability problems.

Active Magnetic Bearing Online Levitation Recovery through μ-Synthesis Robust Control
Actuators, 2017 A rotor supported on active magnetic bearings (AMBs) is levitated inside an air gap by electromagnets controlled in feedback. In the event of momentary loss of levitation due to an acute exogenous disturbance or external fault, reestablishing levitation ...
