地震作用下 MSCSS 控制优化参数研究
On optimizing control parameters for suppressing vibration of MSCSS under earthquake excitation
摘要
Abstract
Sections 1 and 2 of the full paper explain our application ,Their core consists of :(1) Based on the complex modal theory ,the expression of the dynamic magnification factor(DM F)about the mega-sub controlled structural system(MSCSS) was derived .We used the dynamic magnification factor(DMF)as structure dynamic response index .(2) According to the change of the DM F in the range of excitation fre-quency which was close to the structural natural frequency of vibration ,it was concluded that different parameter settings (mass ratio ,stiffness ratio ,additional damping ratio ,additional pillar stiffness ratio ) about mega structure and sub structure had different influence on the control effectiveness of the MSC-SS .T he results ,Fig .3 to Fig .11 ,and the analysis preliminarily indicate that the optimal parameter set-tings can indeed improve significantly the self-absorption of shock of MSCSS .This method is applicable to analysis parameter settings of MSCSS with different number of layers .关键词
