Vibration Damping and Control Using Shunted Piezoelectric Materials

Abstract. In this paper, with the aim of providing passive control of structure vibrations a new approach has been proposed for selecting optimal parameters of external electric shunt circuits connected to piezoelectric elements located on the surface of the structure. The approach is based on the mathematical formulation of the natural vibration problem. The results of solution of this problem are the complex eigenfrequencies, the real part of which represents the vibration frequency and the imaginary part corresponds to the damping ratio, characterizing the rate of damping. A criterion of search for optimal parameters of the external passive shunt circuits, which can provide the system with desired dissipative properties, has been derived based on the analysis of responses of the real and imaginary parts of different complex eigenfrequencies to changes in the values of the parameters of the electric circuit. The efficiency of this approach has been verified in the context of natural vibration problem of rigidly clamped plate and semi-cylindrical shell,, which is solved for series-connected and parallel -connected external resonance (consisting of resistive and inductive elements) R-L circuits. It has been shown that at lower (more energy-intensive) frequencies, a seriesconnected external circuit has the advantage of providing lower values of the circuit parameters, which renders it more attractive in terms of practical applications.

“…In this case, the piezoelectric element is used in combination with an electrical network, usually called a 'shunt network' that can be designed to add damping to the structure. The use of different kind of shunts for vibration control and damping was reviewed by Lesieutre (1998). Among the several types of electric networks that can be used to shunt piezoelectric transducers, the inductive shunt that results in a resonant LC network has received most attention in the recent years.…”
