新TCMDの模型構造物に対する自由及び強制振動実験

抄録

The tuned cradle mass damper (TCMD) relies on the motion of a swing mass on a curved surface to dissipate structural vibration energy. The objectives of this study are to obtain constant swing speed of the TCMD for a large amplitude of the swing and to verify its performance through experiments when the structure is under free and forced vibration. In order to obtain a constant speed of the device, the variable radius of the curved surface were calculated by using simple pendulum dynamics. For this study, the damper was installed in a one-story simple rigid frame model with a frequency of approximately 1 Hz.
