ABSTRACT In the design of tuned mass dampers (TMDs), the mass of the TMD is an important performance factor. Generally, the best optimum performance is seen for the maximum mass which is restricted by the loading capacity of the main system. In the presented study, the optimum period and damping ratio of TMD for various single degree of freedom (SDOF) structures are investigated for different mass ratios. In the methodology, a metaheuristic algorithm called flower pollination algorithm is employed. The optimization objective is the minimization of maximum amplitude of the transfer function of the system, which is generally seen at the critical frequency of the structure. According to the results, the frequency or period ratio is generally only related to the mass ratio, but the main structure period plays a great role on the optimum damping ratio. |
