Abstract
This paper proposes the device that can preserve the vibration energy as elastic energy. The proposed system that can store energy is composed of a spring and two variable dampers used by semi-active control in vibration control. A spring and a variable damper are set up in parallel, and a variable damper is installed to it in the series. In this study, the basic algorithm is proposed to store the vibration energy as elastic energy in the first natural frequency and excite the main system in other high frequency by the stored energy. Finally, effectiveness of the proposed system is confirmed by the simulation.
