反扰力振动控制理论及其在井塔消振中的应用

应用反扰力振动控制方法，通过施加一个与原扰力在相位上相反的控制力，来抵消原扰力对结构的影响。此法用于实际的矿井井塔建筑结构消振工程，取得了消振９０％以上的显著效果，从而证实了此法的正确性和有效性。此法在动力荷载扰力作用下的建筑结构振动控制工程中，具有重要的应用价值

Anti Disturbance Force Vibration Control and Its Application in Vibration Control of Winding Tower

A method of anti disturbance force vibration control is suggested in this paper. A control force in the reverse phase to the disturbance force is applied to eliminate the effect of the disturbance force on the structure. The application results of this method in the practical structure vibration suppression engineering of winding tower of coal mine are introduced in this paper. It is shown in those results that the 90% of the vibration amplitude of the structure is eliminated and the effectiveness of the method suggested in this paper is further verified. In the application of control engineering of building structure vibration actuated by the disturbance force of power loading, this method has also its important reference value.
