    Abstract: To address the issues of sedimentation of the working medium,high sealing requirements, and rapid increase in stiffness under medium- and high-frequency excitation leading to severe energy dissipation in traditional magnetorheological dampers, a magnetorheological composite material with good sedimentation stability and low sealing requirements was prepared and tested. An improved Herschel–Bulkley model was established to characterize the mechanical properties of the composite material. Furthermore, a shear magnetorheological damper was designed and manufactured based on the composite material, and the performance response law of the damper under medium- and high-frequency excitation was tested by designed experiments. The results show that the dynamic stiffness of the damper increases from 4.83 × 105N/m to 6.32 × 105 N/m when the test frequency is increased from 5 Hz to 20 Hz under the current excitation of 3A, and the single-cycle energy consumption of the damper under the full-band is about 0.037J, which verified the energy consumption capacity of the designed magnetorheological damper under medium- and high-frequency vibrations.
