摘要:
在结构发生风振响应时,由设置在结构上的双重调频质量阻尼器(MTMD)控制装置被动地产生一组控制力,来减小和抑制结构的风振响应。其中,MTMD的参数取值对MTMD的控制效果有很大的影响,文中对MTMD的频带宽度、调频质量阻尼器(TMD)个数和阻尼比等基本参数进行了研究。根据RI=Min.Max.[DMF]特定的评判标准来评估MTMD的最优参数对控制效果的影响。通过数值分析,研究了MTMD系统各设计参数之间的关系,初步给出了MTMD最优基本参数,对以后MTMD的参数选取提供参考。
Abstract:
When the structure responded to the wind vibration,the multiple tuned mass damper(MTMD)control device set on the structure passively produced a set of control force, to reduce and inhibit the wind-induced vibration of the structures.The parameter selection of MTMD had great influence on its control effect.Therefore,basic parameters,such as the band width,the number of TMD and the damping ratio were studied.By the special RI=Min.Max.[DMF] evaluation standard,the influences of the optimal parameters of MTMD on the control effect were evaluated.Through numerical analysis,the relationship between the various design parameters in MTMD system was studied,and the optimal basic parameters of MTMD were given.
