摘    要:对于有正交阻尼特性的大型结构在安装TMD系统进行减振后,新生成的组合系统将失去正交阻尼特性,从而难于用实模态进行解耦降阶。本文提出一种直接解法,利用原结构的实模态,精确迅速地计算组合系统的强迫振动。

关 键 词:结构  振动  控制  调质阻尼器  模态

Abstract:If one or more TMD systems are installed, the resulting structures will become non-proportionally damped. And it is usually unable to uncouple the equations of motion unless complex modes are used, which will considerably increase the computational effort. The presentpaper proposes a direct algorithm to analyze such problems based only on the real modes. The method is very efficient, and no divergency problem will occur because it is an accurate direct method and does not require any iteration.
Keywords:structure  vibration  control  tuned mass damper  mode
