Performance Tests and Hysteresis Model of MRF-04K Damper
Magnetorheological (MR) fluid is a kind of smart material whose rheological properties can be rapidly varied by application of a magnetic field. To take full use of the advantages of MR fluid for devices, a double-ended shear mode combined with a valve mode MRF-04K damper has been designed and manufactured, and the dynamic characteristics of the damper under sinusoidal excitation were experimentally studied. The maximum force at a full magnetic field strength is about 20 kN, while the maximum power required is less than 50 W. To accurately reproduce the dynamic behavior of the MRF-04K damper, the modified Bouc-Wen model has been investigated. Comparison with the data between the experimental and the predicted indicates that the modified Bouc-Wen model can accurately portray the behavior of the MRF-04K damper and is appropriate for use in control system design for civil structures.
