FPS型TMD變摩擦技術之振動台試驗與分析

本研究利用FPS型隔震系統的摩擦消能，將其應用在TMD上，稱作「VFPS型TMD」（Variable Friction Pendulum System of Tuned Mass Damper），首先理論的部分，透過一般的單擺週期公式，推導出含有摩擦係數的週期公式，再利用試驗輸出的位移-時間圖，我們能得知各曲盤的週期，與理論算出的週期進行比較，最後利用程式對試驗做驗證，能得出相近的位移-時間圖。

In this study, we applied the friction pendulum system (FPS) seismic isolation system as the energy dissipater to the tuned mass damper (TMD), and developed the “Variable Friction Pendulum System of Tuned Mass Damper.” At the beginning, the equation of the period of a simple pendulum was used and modified to include the coefficient of friction. The periods of baseplates with curved surface were determined using the experimental output of the time-displacement relationships. The periods obtained from the experiments were then compared with that calculated from the theoretical equation. It was found that similar time-displacement diagrams were obtained, and the time-displacement relationships derived using the Matlab program can be verified by the results of the experiments of this study.
