    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.

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.

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.

The design method is based on the numerical optimization technique whose objective function is the active control power requirement of the damping system.

The vibration suppression performance, which is evaluated by the maximum value of the gain of the frequency response function of the structure, is by: 1. Effective passive vibration damping of flexible structures may be obtained by introducing reso- nant RLshunt circuits, where an inductance Land a resistance Rforms an additional resonance together with the inherent capacitance C of the piezoelectric transducer [3, 4].
