针对水平地震作用，系统分析了ＴＭＤ在单层鞍壳振动控制中因质量变化、分布位置变化、所控振型个数变化对其结构控制效果的影响及其敏感性问题．并得出了一些重要结论．
In view of the horizontal seismic action, the influence of TMD on the structure control effect and its sensitivity due to the change of mass, distribution position and the number of controlled modes are analyzed systematically in single layer saddle shell vibration control. And come to some important conclusions.
