Combined Piezoelectric-Hydraulic Actuator Based Active Vibration Control for Rotordynamic System Academic Article uri icon


  • Previous research by the authors concentrated on using piezoelectric actuators for active vibration control (AVC) of rotating machinery. The current workextends this by positioning the piezo-actuator remotely from the controlled structure and transmitting the control force via a hydraulic line and two pistons. Liquid plastic (LP) is employed as a transmission fluid to obtain a high bulk modulus and low leakage. The paper presents results for bulk moduli measurement, and bench and rig tests for the entire actuator system. These results show the high effectiveness of the hybrid actuator for controlling vibrations on alaboratory rotor test rig. 1995 by ASME.
