A　new-type　damper-Inverse　Control　MRF　Damper　was　designed　and　made　based　on　the　design　principle　of　the　magneto-rheological　damper.　The　performance　test　of　the　MRF　damper　has　been　carried　out　on　a　small　shaking　table　with　focus　on　studying　the　working　performance　of　the　damper　under　high　frequencies　(10-50　Hz).　In　addition,　the　modified　Bouc-Wen　model　was　adopted　to　fit　the　tests　data.　The　results　are　as　follows:　(1)　It　is　feasible　for　the　inverse　control　of　the　damper　to　be　implemented　by　combining　the　permanent　magnetic　and　the　electro-magnetic　field.　The　application　of　the　isolating　magnetic　hoop　can　assure　the　magnetic　lines　to　run　along　the　theoretical　designed　path,　and　also　raise　the　durability　of　the　damper　by　avoiding　the　direct　contact　between　the　coils　and　MR　fluid.　(2)　The　modified　Bouc-Wen　model　can　well　simulate　high-frequency　performances　of　damper.　It　provides　a　theoretical　foundation　for　application　of　the　kind　of　damper　under　high-frequency　waves.　(3)　It　is　shown　from　the　test　that　the　force-displacement　delay　curve　is　satiated,　and　the　force-velocity　curve　coincides　well　with　the　theoretical　one.　The　parameters　of　the　modified　Bouc-Wen　model　coule　be　taken　as　nearly　stable　values　in　the　15-50　Hz　range.
