速度的一种新类型可调节的调节质量更潮湿(TMD ) 由推动发电机和离合器组成被介绍。力量推动被电磁石和弹簧的加入的操作产生，先生水坝 pers 被用作离合器。速度调整的规则根据 TMD 的工作机制被建立。分析节目在 VBplatform 上被开发。有被动 TMD 和速度的 SDOF 结构的地震反应可调节的 TMD 被分析。结果证明(1 ) 被动 TMD 的控制有效性通常是不稳定的；(2 ) 建议半活跃的 TMD 的控制有效性比被动 TMDsunder 典型地震地面打手势是好一些的；并且(3 ) 不同于被动 TMD 系统，建议速度甚至当主要结构性能在严重地震期间变得无弹性时，可调节的 TMD 展出好控制有效性。

英文摘要：

A new type of velocity adjustable tuned mass damper （TMD） consisting of impulse generators and clutches is presented. The force impulse is generated by a joining operation of electromagnets and springs and MR dampers are used as clutches. Rules for velocity adjustment are established according to the working mechanism of TMD. The analysis program is developed on a VB platform. Seismic response of SDOF structures with both passive TMD and velocity adjustable TMD are analyzed. The results show that （l） the control effectiveness of passive TMDs is usually unstable; （2） the control effectiveness of the proposed semi-active TMDs is much better than passive TMDs under typical seismic ground motions; and （3） unlike the passive TMD system, the proposed velocity adjustable TMDs exhibit good control effectiveness even when the primary structure performance becomes inelastic during severe earthquakes.
