Paper Abstract

The paper presents the activities performed by the authors in order to develop and validate an experimental set-up for measurements of damping characteristics of typical materials employed within aeronautical and industrial field for passive vibrations reduction. These activities have been carried out within the research program funded by the European Commission named “F.A.C.E.” (Friendly Aircraft Cabin Environment). The set-up has been designed to operate through a PC-based acquisition system developed in LABVIEW programming environment. The development of the experimental damping measurement set-up is based on the principle of the “Oberst beam”, and it has been improved to allow the implementation of different approaches with “contacting” sensors and actuators. The influence of the damping on the stability and reliability of the results will be investigated, by evaluating the effect of the beam thickness to the applied damping thickness ratio. The results will be presented for some damping treatments like “constrained layers” as far as for rubbery materials commonly employed within the aeronautical field. These activities are aimed to the implementation of a better damping modelisation of a typical finite element model of light structures.
