| 摘 要： | 本文提出了一种新的控制策略——多重双重调谐质量阻尼器(以下简称为MDTMD)。MDTMD系统参数的可能组合形成十种MDTMD模型，本文评价其中最易制作的一种MDTMD模型。利用定义的优化目标函数，评价了MDTMD的控制性能。数值结果表明MDTMD比双重调谐质量阻尼器(DTMD)具有更好的有效性和对频率调谐的鲁棒性。但MDTMD的冲程大于DTMD的冲程。

| Abstract: | The new control strategy of the multiple dual tuned mass dampers (MDTMD) is proposed in this paper to attenuate undesirable oscillations of structures under ground motion. The ten types of MDTMD can be formed in terms of the MDTMD system parameter combinations, whereas the MDTMD with the simplest manufacturing is chosen here. Employing the goal function defined for the optimum searching, the parameter studies have been performed to evaluate the control performance of the MDTMD. The results indicate that the MDTMD provides better effectiveness and robustness to the change in the frequency tuning than the dual tuned mass dampers (DTMD) with equal total mass. |
