Preisach 모델을 이용한 ER 유체의 온도별 히스테리시스 특성고찰

초록

This paper presents a hysteresis model of an ER fluid itself.In order to do this, the Preisach model is modified to take account for congruent and wiping-out properties of the ER fluid. The proposed model is verified by comparing the predicted hysteresis loop with the measured one. This is undertaken under various operating temperatures of the ER fluid. In addition, the Preisach model is compared with conventional Bingham model in terms of the field-dependent damping force trajectory.
