| Abstract: | A kind of new typed magnetic rheology damper was designed in this paper; it suits the vibration control of multi degree of freedoms. This damper adopted the split typed structural design and solved problems of sedimentation, over heating of magnetic rheology liquid, wiring difficulty, and the design of the damping channel was not to the utmost reasonable etc., and has the advantages of easy assembling, good heat radiation, simple of structure and high efficiency etc., The modeling was carried out on the magnetic rheology damper according to Bingham model, and adopting the Simulink to conduct simulation. Influences of controlling current, excitation frequency and amplitude on the damping characteristics of damper were analyzed. |
