Název v původním jazyce

Active vibration control of hydrodynamic bearings to prevent instability caused by an oil film

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 controllable journal bearing prototype is a part of a test stand, which is consisting of a rotor driven by an inductive motor up to 23 000 RPM. The actively controlled journal bearing consists of a movable bushing, which is actuated by two piezoactuators. The journal vibration is measured by a pair of proximity probes. The control system enables run-up, coast-downand steady-state rotation. A real-time simulator dSpace encloses the control loop. Force produced by piezoactuators and acting at the bushing is controlled according to error signals derived from the signals produced by the proximity probes. The activevibration control extends considerably the range of the operational RPM.
