多重调谐质量阻尼器参数优化的一种改进算法及其应用
|
摘要
提出了一种抑制主系统风振响应为主兼顾质量调谐阻尼器(TMD)子系统相对位移响应的参数优化算法,据此对控制九江桥吊杆风振的多重调谐质量阻尼器(MTMD)系统的参数优化设计进行了研究,结果表明:按通常以主系统响应最小为目标的MTMD参数优化算法所得的参数,TMD子系统的相对位移响应过大,其构件易疲劳损伤,影响减振效果,增加维护成本。按改进后的优化算法,可获得更合理的结果。
A parametric optimization algorithm of multiple tuned mass damper(MTMD) systems considering confinement of the relative displacement response of TMDs is proposed for the practical use of the wind-induced vibration control of the hangers on Jiujiang bridge.The parametric optimization design of an MTMD system which is attached to a hanger on Jiujiang bridge is studied.It is found that the relative displacement response of TMDs is so large as to induce the components damage of TMDs,reduce the vibration control efficiency and increase the maintenance cost.The improved parametric optimization algorithm offers more reasonable results.
