Active vibration damping is a well known application to efficiently damp
the vibrations of mechanic machines, vehicles and other flexible structures. For
the design of an appropriate control system often piezo electric ceramics are used.
Actuator patches are commonly used for the active damping of thin structures such
as beams and plates. Stack actuators are mostly implemented in truss structures as
active members. When the structure to be controlled has considerable stiffness or
the actuator cannot be integrated in the structure itself a different kind of actuator
type becomes necessary. In this paper an actuator/console concept is presented
that combines the advantages of patch and stack actuators, thus leading to a
concept that generates a pair of bending moments with considerable amplitudes.
Finally, the proposed concept is shown to be capable of effectively reducing flexible
vibrations of a simple laboratory beam experiment.
