多自由度Maxwell结构基于传递矩阵法的风振响应解析法
Analysis of wind induced vibration response based on transfer matrix method for multi-degree freedom Maxwell structure
摘要
Abstract
The structure of multi-degree freedom Maxwell damper is studied.First,the multi-degree freedom structure is expanded by first mode.Single degree freedom motion equation is obtained.As the equation does not have the classical damping,the analytical expression of the generalized displacement and the generalized velocity is obtained by the transfer matrix method.Then,by random vibration theory,the response variance of the displacement and velocity structure is divided into a series of standard vibrator displacement and velocity response of a linear combination of the variance.Finally,the structural random response and equivalent wind load are obtained by the Davenport spectrum.A random wind vibration response analysis method is established with Maxwell structure.A numerical example is given.关键词
