Through characteristic testing of a MR damper, its force-displacement and force-velocity relationship under different currents were studied; the main features of a friction-type MR damper were analyzed.

Through concluding the structures and characteristics of existing megnetorheological fluid dampers,a new type of magnetorheological fluid damper was proposed.
