Outline of Final Research Achievements

In this study, a self-powered active seismic isolation device which achieves active control using regenerated vibration energy is proposed. This device doesn't require external energy to produce control force. The purpose of this study is to propose the seismic isolation device having charging function and to optimize the control system and passive elements such as spring coefficients and damping coefficients using genetic algorithm.
As a result, optimized model shows good performance in terms of vibration reduction and electric power regeneration by numerical analysis and experiment.
