In this paper, dynamic characteristis of a MR damper are investigated with an experimental setup. Based on the experimental data, an improved mechanical model for MR damper is proposed and the parameter were selected to fit the experimental data. The model consists of a hysteresis part and a variable viscous damper proportional to the added voltage. In addition, two on-off damper control policies based on the product of relative velocity and relative displacement are proposed. The numerical simulation and experiment are performed to investigate the effects of the two kinds of on-off dampers and conventional on-off damper in the single-degree-of-freedom system. The results show that on-off dampers express the better vibration performance than the uncontrolled MR damper, two proposed on-off dampers have the better performance in the high frequency domian than that of conventional on-off damper, and the controllable MR damper is very effective for vibration control.
