基于定点理论的串联黏滞质量阻尼器参数优化
Parameters Optimization of the Series Viscous Mass Damper Based on the Fixed-point Theory
摘要
Abstract
Based on fixed-point theory,this paper conducted a research on the parameters optimization of a tuned series viscous mass damper (SVMD).Firstly,using the displacement transferring function of SVMD system,the expressions of amplification factors of displacement and acceleration are derived.Then,based on fixed-point theory,by setting the amplitudes of displacement and acceleration minimum,respectively,the corresponding optimal formula of the SVMD system are obtained.Last,using the obtained optimal formula,two kinds of SVMD systems are designed and the optimal dynamic characteristics are compared.It is found that,the SVMDs,respectively designed according to the two conditions,can both effectively suppress the structural response.What's more,with the same mass ratio,the optimal stiffness ratio and additional damping ratio of the SVMD system by minimizing the displacement amplitude are smaller than those of the SVMD system by minimizing the acceleration amplitude.关键词
