摘要

由于中心自振频率的设置,至今研究的多重调谐质量阻尼器器(MTMD)都是由奇数个调谐质量阻尼器 (TMD)所组成。放弃中心自振频率的设置,提出了基于任意整数的多重调谐质量阻尼器。多重调谐质量阻尼器可由任意奇数个或偶数个调谐质量阻尼器组成。使用建立的结构MTMD系统传递函数,定义了结构和MTMD的动力放大系数(DMF)。MTMD最优参数和有效性的评价准则于是可定义为结构最大动力放大系数的最小值的最小化(MIN．MIN． MAX．DMF)。而MTMD冲程的评价准则定义为MTMD中每个TMD最大动力放大系数的最大值。根据定义的评价准则,评价了基于任意整数MTMD的控制性能(包括MTMD的冲程评价)。
To date,researches have been focused practically on the multiple tuned mass dampers (MTMD) with the total system composed of odd number dampers due to setting the central natural frequency. The arbitrary integer based MTMD is proposed through giving up the central natural frequency hypothesis .The total number of dampers may be selected as odd or even. Employing the formulated transfer functions of the MTMD structure sys tem, the dynamic magnification factors (DMF) of the MTMD structure system are defined.The evaluation criteria can then be selected as minimizing the minimum values of the maximum DMF of the structure (min.min.max. DMF) and, in addition,the maximum dynamic magnification factor of each TMD in the MTMD. The control performance of the MTMD (including the MTMD stroke) then is evaluated in terms of the defined criteria.
