Abstract |
This study aims to show the optimal parameters of pendulum type TMD for pendulum type main system and describe the application of pendulum type TMD to Namsan cable car. The pendulum type TMD shows an optimal frequency ratio greater than 1, positive phase difference to the main system, and better performance as the distance between the main system mass and the TMD mass increases. These characteristics are different from those of a parallel 2-degree of freedom system. The performance of the pendulum type TMD was proved to be successful in reducing the wind induced response by more than 50%, and it enables the cable car to be served at a higher wind speed above the wind speed regulation of 9m/s. |
