摘　　要：提出多重双重调谐质量阻尼器(MDTMD)控制策略。MDTMD由任意奇数或偶数的双重调谐质量阻尼器(DTMD)组成。MDTMD参数组合形成十种MDTMD模型即MDTMD(I-1)-MDTMD(I-5)模型和MDTMD(II-1)-MDTMD(II-5)模型。利用定义的优化准则,评价了MDTMD(I-1)的控制性能。数值结果表明MDTMD(I-1)比DTMD和基于任意整数多重调谐质量阻尼器(MTMD)和基于奇数MTMD具有更好的有效性和鲁棒性。但MDTMD冲程大于DTMD冲程;MDTMD小TMD冲程大于MTMD冲程。The new control strategy by using the multiple dual tuned mass dampers(MDTMD) is proposed to attenuate undesirable vibration of structures under the ground acceleration.The MDTMD may consist of odd or even total number of dual tuned mass dampers(DTMD).Ten combination types of MTMD [i.e.MDTMD(Ⅰ-1)-MDTMD(Ⅰ-5)and MDTMD(Ⅱ-1)-MDTMD(Ⅱ-5)] are formed in terms of the possible composition of MDTMD system parameters.Employing the criteria defined for optimum searching,the parametric studies are carried out to evaluate the control performance of the MDTMD(Ⅰ-1).The results indicate that the MDTMD(Ⅰ-1) provides better effectiveness and robustness than both DTMD and multiple tuned mass dampers(MTMD)(including the arbitrary integer based MDTMD and odd number based MTMD) with equal total mass.However,the MDTMD stroke is greater than that of DTMD and the stroke of the smaller mass block in MDTMD is larger than that of MTMD.
