Design and simulation of a self- sensing MR damper
This paper presents the design and development of a self-sensing magneto-rheological (MR) damper. The MR damper is constructed of piston, inner tube and the outer cover with one excitation winding mounted to the piston and an induction winding to the middle of the inner tube and the outer cover. Therefore when external excitation is deployed to the excitation winding, we can derive induced voltage from the induction coil with the piston movement, thus superposes the information of the damper's motion to the induced voltage signal which can be further modulated that feedback appropriate controlling signal to the experimental devices. In this essay, both the design concept and optimization of the self-sensing MR damper prototype are discussed in a detailed manner.
