摘要：

Severe　vibration　of　underground　structures　may　be　induced　under　blast　loads.　According　to　the　characteristics　of　the　explosion-induced　ground　shock　wave,　a　new-type　damper,　inverse　control　magnetorheological　(MR)　damper　was　designed　to　control　the　vibration.　The　high-frequency　performance　test　of　the　MR　damper　was　carried　out　on　the　small　shaking　table.　It　is　shown　that　the　performance　can　be　modeled　by　the　use　of　the　modified　Bouc-Wen　model,　and　the　parameters　of　the　model　keep　stable　in　the　range　of　15-50　Hz.
