Abstract

This paper describes the development of a structural model of a high speed rotor for the examination of active vibration control in rotor dynamics. Suppression of lateral bending vibrations of the elastic shaft is realized by means of surface-bonded piezoceramic actuator patches on the shaft surface. Models for actuator implementation are derived. Simulations demonstrate the effectiveness of this approach. To validate the simulation, a rotor test-rig was built. The characteristics of the system model with implemented actuators are compared to experimental tests. Both results show good agreement.
