Abstract:
Modelling and simulation for controllable dashpot dampers using magneto- or electro-rheological
fluids 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 the
performance of a prototype shear damper. The damper performance in the quasi-static state is being
assessed based on the shear strength, generated in the semi-solid plug formed when the controllable
fluid is magnetized, versus damper displacement or velocity. Employing curve-fitting technique,
validation of the proposed quasi-static parameteric model was carried out accordingly. Results
indicate good agreement with the proposed model.
