본 논문에서는 무선 진동제어 시스템을 구성하고, 모형 구조물을 대상으로 구성된 시스템의 진동제어효과를 실험적으로 검증하고자 하였다. 진동제어 실험은 가진기를 이용해 보의 1/4 등분점에서 일정하게 가진한 상태에서, 보 중앙점에 수직방향으로 설치된 MR 댐퍼를 이용해 진동을 제어하였으며, 보의 2/4 등분점에서의 가속도 응답을 획득하여 제어효과를 평가하였다. 최종적으로 본 논문에서 구성된 무선 센서 네트워크 기반의 실시간 피드백 진동제어 시스템은 비록 제한적인 명령 체계에서 검증되었지만, 실시간적으로 목적된 제어명령의 발생시킴으로써 구조물의 진동을 효과적으로 감소시키는 것을 확인하였고, 추후 다양한 준능동 제어 알고리즘을 적용한 구조적 응답 제어시스템으로의 활용 가능성을 제시하였다.
Abstract
This paper aims to constitute a feedback vibration control system using wireless sensor networks and experiment it on a model structure to verify its effectiveness. The vibration control experiment was performed by shaking the 1/4 point of beam with a shaker. At the moment of shaking, we controled the vibration with MR damper which was placed vertically on the center of beam. Simultaneously, by acquiring acceleration response at the 2/4 point of beam, we evaluated the effectiveness of control capability. Although the realtime feedback vibration control system constituted in this paper is effective only within a limited command system, it has been proven that the system was able to effectively decrease the vibration of structure by generating a control command aimed for realtime purpose. The system also showed a possibility to be used as a structural response control system adapting a variety of semi-active control algorithm.
