DAMPING OF COMPOSITE BOOMS THROUGH ACTIVE PIEZOELECTRICINTERFACE AND PIEZOELECTRIC PATCHES

摘要

This paper investigates the active damping of tubularCFRP booms by means of piezoelectric hexapods, andpiezoelectric conformable patches. Background theoryis developed, and numerical simulations representativeof the DARWIN-Structure telescope are presented toassess the efficiency of the damping systems. This studyis supported by laboratory demonstrators described inthe last part of the paper.
