The usage of acceleration signal to control magneto-rheological fluid damper

A semi-active controllable linear magneto-rheological (MR) fluid damper is described and studied in this paper. The damping characteristics of the damper may be adapted in real time to the user's requirements. Such dampers can then be used to eliminate vibrations in applications like vehicles and different machines. In this paper a simple control method, which uses an acceleration signal to switch the damper on and off is proposed. The construction of such a control system is described and finally experimental results of oscillation damping are presented.
