DAMPING SYSTEM
To provide a damping system for damping vibration of a boiler building.SOLUTION: Active type damping devices 2a, 2b and damping devices 2c, 2d are arranged respectively along two directions intersecting with each other in a horizontal surface on an apex side of a boiler building 100. A vibration detecting device for detecting vibration on the boiler building 100 coupled with translational vibration and torsional vibration generated by acceleration of the boiler building 100; mass detectors 4a, 4b detecting masses of bunker 105a, 105b; a storage part; and controllers 6a, 6b, 6c, 6d. When the mass detector 4a, 4b receive detecting mass value of the bunkers 105a, 105b respectively, the controllers 6a, 6b, 6c, 6d start to read data of control parameters optimum for the masses from the storage part. The controller 6a, 6b, 6c, 6d send instructions to the damping devices 2a, 2b, 2c, 2d based on the read control parameters to damp the coupled translational vibration and torsional vibration when the coupled translational vibration is exited on the boiler building 100.SELECTED DRAWING: Figure 1
【課題】 ボイラ建屋の制振を行う。【解決手段】 ボイラ建屋１００の頂部側に、水平面内で交差する２方向に沿い配置された能動型の制振装置２ａ，２ｂおよび制振装置２ｃ，２ｄを設ける。ボイラ建屋１００の加速度により、ボイラ建屋１００に生じる並進振動とねじり振動が連成した振動を検出する装置と、バンカ１０５ａ，１０５ｂの質量を検出する質量検出器４ａ，４ｂと、記憶部と制御器６ａ，６ｂ，６ｃ，６ｄを備える。制御器６ａ，６ｂ，６ｃ，６ｄは、質量検出器４ａ，４ｂからバンカ１０５ａ，１０５ｂの質量の検出値を受け取ると、記憶部から、その質量で最適となる制御パラメータのデータを読み出す。ボイラ建屋１００に連成振動が励起されると、制御器６ａ，６ｂ，６ｃ，６ｄは、読み出した制御パラメータに基づく指令を制振装置２ａ，２ｂ，２ｃ，２ｄへ与えて、連成振動の並進振動とねじり振動の制振を行う。【選択図】図１
