Abstract(s)

This paper aims to evaluate the long term use and aging effects on the electromagnetic and mechanical characteristics of a magneto-rheological (MR) fluid sponge damper. The device was used in several experimental research projects for ten years followed by four years of inactivity. It was used back in the last year during an experimental campaign to evaluate its effectiveness after these years of heavy use and inactivity. Thus, the dynamic behaviour of a MR fluid sponge damper at several mechanic and magnetic excitations is studied. Finally, the possible causes of the variation in the electromagnetic and mechanical responses of the MR damper with respect to the initial specifications are discussed.
