Vibration Attenuation by a Combination of a Piezoelectric Stack and a Permanent Magnet

open access: yesShock and Vibration, 2012
The present work proposes a non-contact vibration attenuator made up of a permanent magnet mounted on a piezoelectric stack. Two such actuators are made to work simultaneously in a 'twin-actuator' configuration.
