摘    要:研究了基于Maxwell型阻尼器的多重调谐质量阻尼器(MTD—MTMD)在控制结构地震反应方面的最优动力特性。利用建立的设置MTD-MTMD时结构的传递函数,定义了设置MTD—MTMD时结构的动力放大系数(DMF)。将MTD-MTMD的优化准则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)。利用定义的优化准则,评价了Maxwell型阻尼器的松弛时间系数(RTC)对MTD—MTMD最优参数和有效性的影响。利用最大的MTD—MTMD动力放大系数(DMF),评价了RTC对MTD-MTMD冲程的影响。

关 键 词:Maxwell型阻尼器多重调谐质量阻尼器(MTD-MTMD)  动力放大系数(DMF)  松弛时间系数(RTC)  最优化

Abstract:The performances of Maxwell-type damper based multiple tuned mass dampers (MTD-MTMD) are investigated in reducing the response of structures under earthquakes. Employing the formulated transfer function of the structure with the MTD-MTMD, the dynamic magnification factor (DMF) of the structure with the MTD-MTMD is defined. The criterion for the optimum searching can then be selected as minimizing the minimum values of the maximum DMF (Min.Min.Max.DMF). Employing the criterion, the effect of the relaxation time constant (RTC) on the optimum parameters and effectiveness of the MTD-MTMD is evaluated. The effect of RTC on the stroke of the MTD-MTMD is evaluated in terms of maximizing the dynamic magnification factor (DMF) of the MTD-MTMD.
Keywords:Maxwell-type damper based multiple tuned mass dampers (MTD-MTMD)  dynamic magnification factor (DMF)  relaxation time constant (RTC)  optimality
