Magneto-rheological shear dampers: Quasi-static modelling and simulation

Modelling and simulation for controllable dashpot dampers using magneto- or electro-rheologicalfluids have been carried out extensively, however, only few have considered shear dampers.Experiments at the University of Technology, Sydney (UTS) are being conducted to characterize theperformance of a prototype shear damper. The damper performance in the quasi-static state is beingassessed based on the shear strength, generated in the semi-solid plug formed when the controllablefluid is magnetized, versus damper displacement or velocity. Employing curve-fitting technique,validation of the proposed quasi-static parameteric model was carried out accordingly. Resultsindicate good agreement with the proposed model.
