Test and theory for robust active vibration control of rotor- bearing systems utilizing piezoelectric actuators
(1993)
This research focuses on designing effective control strategies using piezoelectric actuators for control of vibrations of flexible rotor-bearing systems. The actuators are completely described and the elements of feedback ...
A three-dimensional viscous flow model of stator/rotor interaction in turbomachines
(1990)
The current numerical model takes into account the full three-dimensionality and cyclic fluctuations of the flow variables in a turbomachinery stage. The cyclic fluctuations are the result of circumferential irregularities ...
Thermoelastohydrodynamic tilt pad journal bearing simulation and application to rotor-bearing model
(1993)
A general approach for incorporating heat transfer and elastic deformation effects into a tilt pad journal bearing simulation model is presented. A global analysis method is used, which includes variable viscosity and heat ...
