Paper Abstract

Control-structure interaction (CSI) during structural vibration control system has been investigated in some current literatures. However, the interaction between MR damper and flexible stay cable has not been reported. In this paper, experimental investigation on vibration control is carried out on a stay cable model incorporated with one small size magneto-rheological (MR) fluid damper taking into account the interaction effect of the stay cable and the MR damper. Experiments on the vibration control of the stay cable model attached with the MR damper with different constant current input indicates the obvious interaction between the stay cable and the MR damper. A novel model of MR damper with constant current input coupled with stay cable is proposed to better predict the MR damper’s behavior considering the interaction effect between the stay cable and the MR damper. The proposed coupling model is validated by the numerical simulations using the experimental results.
