솔레노이드 엑츄에이터의 해석과 설계에 관한 연구 = A study on analysis and design of solenoid actuator

국문 초록 (Abstract)

솔레노이드 엑츄에이터는 전기, 자기, 기계 시스템이 결합된 형태로 동작한다. 솔레노이드는 구조가 간단하고 저렴하여 직선 구동용 엑츄에이터로 많이 사용된다. 현재 개발되어 있는 엑츄에이터 들은 주로 밸브용으로 개발되어 고속응답 특성을 중시한 나머지 직선 구동용 엑츄에이터로는 적합하지 못하다. 본 논문에서는 직선 구동용 엑츄에이터가 갖추어야 할 요건과 제조성에 대하여 설명하였다.

솔레노이드에서 일어나는 물리적인 현상을 표현하는 수학적 모델을 정리하고 복합 해석하였다. 측정장치 제작하여 동특성을 측정하였으며, 해석 결과와 비교하여 해석의 타당성을 검증하였다. 또한 솔레노이드의 기능 요건과 제조성을 고려하여 최적 설계를 찾을 수 있는 방법을 제시하였다.
