基于虚拟激励法的结构ATMD风致振动控制的研究
摘 要
本文开展了结构风致振动的主动调谐质量阻尼器(ATMD)控制的研究。基于虚拟激励法,针对Davenport风谱激励作用下的单自由度(SDOF)结构,建立了结构ATMD系统的动力方程,定义了ATMD的最优参数和有效性评价准则。基于定义的评价准则,数值地研究了结构ATMD风致振动控制的最优参数和有效性。数值结果表明,进行合理化设计的ATMD能够有效地抑制结构的风致振动。此外,运用ATMD装置具有明确的物理意义以及灵活的设计形式,便于针对不同的激励和风振响应状况设计变增益控制,以提高ATMD控制效率及满足控制力和行程的实际限制。

Researches of Wind-Induced Vibration Control on Structure Using Active Tuned Mass Damper
ABSTRACT
This text processed a research of which the Wind-Induced Vibration of structure controlled by Active Tuned Mass Damper (ATMD). According to the method of dummy inspirit, to single freedom degree (SDOF) structure under the function of Davenport wind table encouraging, the motive square distance of the system ATMD is built up, the superior parameter and the rule of judgment of the validity controlled by ATMD are defined. According to definition of the rule of judgment, the superior parameter and the rule of judgment of the validity controlled by ATMD is researched accurately. The result proved that the ATMD which was designed rationally can availably reduce the Wind-Induced Vibration of structure. Moreover, it’s meaningful and flexible to use the ATMD in order to control the effect caused by the wind with the different frequency expediently and improve the control efficiency of ATMD and meet actual limit of journey and ability of control.
Keywords: ATMD, tall building, wind vibration, optimize design.
