[Structures Piézo-ÉlectroMécaniques (PEM) : contrôle passif de vibrations en utilisant des transducteurs piézo-électriques distribués]
Une structure piézo-électromécanique (PEM) se compose par un élément structurel hôte, une rangée uniformément distribuée de transducteurs piézoélectriques et un circuit électronique passif (agissant comme contrôleur) pour établir leur interconnexion électrique. Un tel circuit doit être conçu pour assurer la transduction la plus efficace de l'énergie mécanique en électrique. Les circuits nécessaires sont synthétisés pour des barres, des poutres et des plaques et les performances des structures PEM correspondantes sont déterminées. Une fois que des éléments dissipatifs appropriés sont inclus dans le contrôleur on montre que dans les structures PEM les vibrations mécaniques sont atténuées le plus efficacement possible.
A piezo-electromechanical structural member is composed of a host member, a uniformly distributed array of piezoelectric transducers and a passive electric circuit (acting as a controller) interconnecting their electric terminals. Such a circuit has to be designed to assure the most efficient transduction of mechanical into electrical energy. The needed circuits are synthesized for bars, beams and plates and the performances of the corresponding PEM structures are determined. Once suitable dissipative elements are included in the controller, it is proven that, in PEM structures, mechanical vibrations are the most efficiently damped.
