Abstract

Aim of the present paper is to analyze and compare two different models used to study the axial vibration problem of a beam structure actuated by piezoelectric layers bonded to it. Crawley and de Luis [4] have recently set up a distributed dynamic model for both the axial and the flexural dynamic of an actuaded beam structure. Rogers has explored the possibility of describing the dynamic interaction between piezoelectric actuators and a beam structure by means ofa lumped model [5]. In the first section of this paper a completely lumped parameters model will be presented and discussed; the results wiil be compared in the second section with the ones obtained for a distributed model.
