Název v původním jazyce

Active vibration control of hydrodynamic journal bearings

Popis výsledku v původním jazyce

The paper deals with a working prototype of a system for the active vibration control of journal bearings with the use of piezoactuators. The actively controlled journal bearing consists of a movable bushing, which is actuated by two piezoactuators. It is assumed that the journal vibration is measured by a pair of proximity probes. Force produced by piezoactuators and acting at the bushing is controlled according to error signals derived from the proximity probe output signals. The active vibration control was tested with the use of a test rig, which consists of a rotor supported by two controllable journal bearings and driven by an inductive motor. As it was proved by experiments the active vibration control extends considerably the range of the rotoroperational speed.
