＜正＞ A generalized model is synthesized to charaterize the asymmetric hysteresis force-velocity（F-v） properties of the magneto-rheological (MR fluids damper. The model is represented as afunction of the command current, excitation frequency, and displasement amplitude, based on thesymmetric and asymmetric sigmoid functions. The symmetric hysteresis damping properties of thecotrollable MR.damper and properties of the conventional passive hydraulic damper can also bedescribed by the proposed model. The validity of the model is verified by experiments, which showthat the results calculated from the model are consistent with the measured data. In addition, it isshown that the model applies to a wide vibration frequency range. The proposed model has potentialapplication in vehicle suspension design employing the symmetry MR-damper, and also in developingtie asymmetry MR-Damper especially for the vehicle suspension attenuation.
