摘要 建立了随机脉动风载下巨-子型有控结构(MSCS)的动力方程;基于复模态理论,推导了MSCS在随机风载激励下的协方差函数、位移及加速度响应功率谱和均方响应表达式;讨论了子结构质量对MSCS控制效果的影响。 Dynamic equation and method to assemble parameter matrixes for the meg- sub - controlled structure (MSCS) under random wind loads are presented. The coherence function, vibration displacement and acceleration response spectrum, as well as the mean square response expressions are derived on the basis of complex model analysis theory. A parametric study of mega - structure mass that influences the response controlling effectiveness of the MSCS is discussed.
