Vibration Reduction Analysis of Hybrid Control of Stay Cable using EMID and TMD

In order to effectively reduce the cable amplitude, both EMID and TMD are used to reduce the vibration of the stay cable. In this study, the complex eigenvalue method is used to simulate and analyze the responses of the stay cable coupled with an electromagnetic inertial damper and a tuned mass damper. To maximize the modal damping ratio of the coupled system, the optimized parameters of the tuned mass damper and the electromagnetic inertial damper under different mass ratios and inertial mass ratios are obtained, respectively. Compared with the optimized parameters of a single tuned mass damper, the results show that the electromagnetic inertial damper and the tuned mass damper coupled system can provide more additional modal damping ratios for hybrid control of stay cables.
