Damping of Beams with Inserts

Abstract

The purpose of this project is to predict damping effect using beams with inserts for passive damping. This method of passive damping treatment is widely used for structural application in many industries like automobile, aerospace, etc. The experiment is to be carried out to compare the damping of the material without inserts and with inserts of different visco-elastic materials of circular cross sections.
The specimens are prepared from commercial mild steel and Teflon, Bakelite, Perspex as inserts.
The experiment results are shown and from the results it has been concluded that the inserts of high damping capability in the structures increases the damping characteristics of the structure. The graphs obtained from the oscilloscope shows damping of the beams.
