Vibration Limiting of Rotors by Feedback Control,

Abstract

This work reports some experimental findings on a three-mass rotor with four channels of feedback control. The channels are independently controllable with force being proportional to the velocity and/or instantaneous displacement from equilibrium of the shaft at the non-contacting probe locations (arranged in the vertical and horizontal attitudes near the support bearings). The findings suggest that automatic feedback control of rotors is feasible for limiting certain vibration levels. Control of one end of a rotor does afford some predictable vibration limiting of the rotor at the other end. The next step in the work is to move from acoustic drivers to electro-hydraulics so that larger force levels may be experimented with.
