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.

CHARACTERIZATION OF PIEZOELECTRIC STACK ACTUATORS FOR VIBROTHERMOGRAPHY

open access: yesAIP Conference Proceedings, 2011
Vibrothermography, also known as Sonic IR and thermosonics, is an NDE technique for finding cracks and flaws based on vibration‐induced frictional rubbing of unbonded surfaces. The vibration is usually generated by a piezoelectric stack actuator which transduces electrical energy into large amplitude mechanical vibrations.
