Abstract
ABSTRACT This paper presents the methodology to design and optimise a feasibility demonstrator for low-frequency activevibration control of a composite plate. An original approach has been achieved and several problems due to thebehaviour of the piezoceramic explained and solved. 1. INTRODUCTION1.1. Fields of work and possible applications With the point of view of an aerospace manufacturer the field of application of smart materials and structures isvery wide, from health monitoring to active geometry and active vibration control. The purpose is a feasibilitystudy of a demonstrator with the following applications : vibrations, decoupling interfaces, integrated structural vibration damping, dynamic shape control for aerodynamic optimisation. This study is the second step of a larger research program : the first step consisted in the development of the active shape and vibration control of a cantilevered beam which was successfully implemented. The controller based on the old principle of the
