Abstract

Micro-vibration induced by on-board appendages that have mechanical moving parts has always been treated as an useless objective that has to be isolated, in order to comply with a high-resolution mission requirement of the observation satellite. In this study, we proposed a tuned mass damper energy harvester combined with a conventional passive vibration isolator for exhibiting dual functions of both electrical energy harvesting and micro-vibration isolation. The feasibility of the proposed dual-function complex system has been demonstrated through the comparison with numerical simulations, based on the results of basic characteristic tests, and experiments of the harvested power and micro-vibration.

관측위성의 고 해상도 임무요구조건 충족을 위해 기계적 구동부를 갖는 탑재장비로부터의 미소진동은 항상 차폐의 대상으로 존재하였다. 본 연구에서는 차폐의 대상이던 미소진동에 주목하여, 전기에너지 재생이 가능하고 동시에 진동절연이 가능한 복합 시스템 구현을 목표로 동조질량 흡진기 형태의 전자기 하베스터와 결합된 수동형 진동절연 시스템을 제안하였다. 아울러 하베스터의 기본특성 측정시험 결과에 기인한 수치해석과 미소진동시험 및 생성전력 측정시험을 통해 본 연구에서 제안한 복합시스템은 미소진동 절연과 동시에 전기에너지 재생에 유효함을 입증하였다.
