摘要

The study here reported is focused on active vibration control applications performed on plate host structures equipped with electrostrictive patches. In such applications the design of controllers requires to simulate the behavior of the coupled structure. These simulations can then be performed through a Finite Element Method which implies the elaboration of electrostrictive finite elements. The purpose of the present paper is to present the elaboration of a plate electrostrictive finite element with a priori plate assumptions. We underlined in a previous paper that using current as driving input for these actuators would imply simplifications in active vibration control. We thus set out here finite elements for both current driven, and voltage driven actuators, with the view of highlighting theses simplifications. The elements here developped are characterized by the reduction of the initial electromechanically coupled problem to a purely mechanical one. Comparisons of numerical simulations of the control of the vibration of an elastic beam using different models of the system is moreover presented in this article.
