摘要
多重调谐质量阻尼器(MTMD)是由多个固有频率成线性分布的调谐质量阻尼器(TMD)组成。可能的MTMD系统参数组合形成5种MTMD即MTMD-1-MTMD-5。基于建立的MTMD-1-MTMD-5结构系统传递函数和动力放大系数(DMF),定义了求解MTMD-1-MTMD-5最优参数的优化准则。利用求得的MTMD-1-MTMD-5最优频率间隔、阻尼比和调谐频率比,评价了MTMD-1-MTMD-5的冲程情况。
The multiple tuned mass dampers(MTMD) consist of many tuned mass dampers with a linear distribution of natural frequencies.The five types of MTMD(i.e.MTMD1-MTMD-5) are formed in terms of the MTMD system parameter combinations available.By resorting to both the transfer functions and dynamic magnification factors(DMF) formulated for the MTMD-1-MTMD-5 structural system,the MTMD-1-MTMD-5 criterion for optimum searching is then defined.Employing the obtained optimum frequency spacing,damping ratio and tuned frequency ratio,the evaluation is then made on the MTMD-1-MTMD-5 stroke.
