Research on Numerical Simulation of Smart Base Isolation System with MR Damper (I)

Abstract:

Rubber bearing base-isolation is well-developed vibration reduction technique and is applied in practical engineering broadly. The nature period of the base-isolation structure applied with rubber bearing is extended. Meanwhile the response of the superstructure is also reduced. But it is noticed that the displacement of isolation layer is too large. So it is required to find a suitable damper to reduce the displacement of isolation layer. Magnetorheological damper has good smart performances- broad controlled band, fast response and demand a little energy. In this paper smart base isolation system, which is combined with rubber bearing and MR damper is applied to structural vibration control, and have numerical simulation e of structure employing RB isolation and smart isolation in different kind and magnitude of earthquake waves. The result indicates the control system is effective.
