The aim of this work is two-fold: to design devices for passive electric damping of structural vibrations by distributed piezoelectric transducers and electric networks, and to experimentally validate the effectiveness of such a damping by: The book concludes with an exhaustive bibliography and index. This book is intended for structural engineers who want to acquire some background in vibration control, and for control engineers who are dealing with flexible structures. It can be used as a textbook for a graduate course on vibration control or active structures.
Background on Vibration Damping Vibration Damping Background. Vibration is a repetitive motion of objects in alternately opposite directions from the equilibrium position when that equilibrium has been disturbed. It occurs in most machines, structures, and dynamic . PASSIVELY DAMPED LAMINATED PIEZOELECTRIC SHELL STRUCTURES WITH INTEGRATED ELECTRIC NETWORKS Dimitris A.

Design of passive piezoelectric damping for space structures. [Nesbitt W Hagood; Jack B Aldrich; Andreas H von Flotow; Langley Research Center.]. When we design the hybrid piezoelectric damping system by using the proposed integrated design method, the number and location of the PZT tiles pairs to be used for the passive and active damping could be optimized in the design problem formulated in Section In this study, however, we select the specified values of the number and location of the PZT tiles pairs to be used for the passive Cited by: 2 J.

This technique, named piezoelectric shunt damping, consists of using a Smart Materials and Structures Smart by: 7. Studies in the past focused on the implementation of semi-passive damping techniques that could significantly reduce structural vibration.
Recently, the performances of these damping techniques have been enhanced by artificially increasing the voltage amplitude delivered by the piezoelectric patches with an external voltage source.

Piezoelectric shunt damping offers a passive solution to mitigate mechanical vibrations: the electromechanical coupling induced by piezoelectric patches bound to the vibrating structure allows the transfer of vibration energy to an electrical circuit, where it can be dissipated in a resistive component.
Piezoelectric transd ucers can also be used for semi-active or passive damping by using electrical shunt circuits, w hich minimizes the effort for additional components like sensors or control.
