Abstrakt: |
In this paper, an inerter is incorporated into the conventional TMD system, and the performance of the novel inerter-based system, namely tuned mass damper inerter (TMDI), for the VIV mitigation of long-span bridges has been studied. A suspension bridge is taken as a numerical example to verify the performance of TMDI, and the optimal parameters of TMDI are determined by the genetic algorithm. A parametric analysis of the control effect of TMDI is conducted to investigate the influence of the mass ratio and inertance ratio of TMDI on its static deformation, control effect, stroke and control force. The results show that with the same mass ratio, TMDI is slightly less effective than TMD, but it can still significantly reduce the vibration amplitude of the bridge deck. The static deformation and stroke of TMDI are much smaller than that of TMD, which saves installation space and makes it more suitable for the vertical vibration control of long-span bridges. |
