| description | Aiming at the problem of the narrow damping frequency band of traditional single-tuned mass damper (STMD), this paper proposes multiple-tuned mass dampers (MTMDs) and six different configurations of tuned mass damper inerter systems (TMDI-Ⅰ–TMDI-VI) for vibration suppression optimization. A long-span steel truss footbridge was selected as the research object, a vibration simulation model of a single-degree-of-freedom pedestrian bridge-damping system was established by Matlab Simulink, and the vibration damping effects of STMD, MTMD, and six TMDI damping systems under human-induced excitation were compared and analyzed. The results indicate that the damping effect of MTMD is better than that of STMD when the self-oscillating frequency of the footbridge is deviated, and its robustness is further improved with the increase in the number of MTMD subunits n. The damping effect of the six TMDI damping systems varies greatly, among which TMDI-III has the best damping effect and robustness, when λ=5%, the damping rate α of the TMDI-III damping system is still able to increase by 8.3% compared with that of STMD. The research results can provide theoretical support for the vibration reduction control of large-span steel truss footbridge. |
