Multi-mode Control Performance of Inertial mass damper in Stay Cable Vibration

摘要：

　　Inerter-based damping devices(IBBDs),which consist of inerter,spring and viscous damper,have been extensively investigated in vehicle suspension systems and demonstrated to be more effective than the traditional control devices with spring and viscous damper only.In the present study,parametric analysis and optimal design of inertial mass damper is developed for multi-mode vibration control of stay cable.The results show that inertial mass damper can provide more damping to the first four modes of cable than the viscous damper does.All the modal damping ratios of the first four modes increase gradually with the increasing apparent mass,but the increasing rates of the second mode and the third mode are more significant than those of the mode one and the mode four.
