Aktivno prigušivanje vibracija krutog rotora kinematskom pobudom blaznica kliznih ležajeva

摘要

Possibilities of active lateral vibration reduction of a symmetric, rigid rotor supported by journal bearings are given.They were obtained by computational modelling. Efficiency of the feedback P and PD controllers in the stablerevolution interval was examined. The linearized rotor system model was used. The results of the theoreticalanalysis are assigned for a testing stand where the bearing bush motions are deactivated by piezoelectric actuatorsconnected to the controllers.
