Abstract

This paper deals with a fabrication method of composite hinge mechanisms for flapping-wing micro air vehicles. The fabrication process includes curing process of Graphite/Epoxyprepregs, laser cutting for high fabrication repeatability, laminating of Graphite/Epoxy prepregs with Kapton film which is used for flexure, and so on. The fabricated hinge mechanism was attached with PUMPS actuators and the measured flapping angle was $173^{\circ}$ when driving voltage was 300V 170Hz.

본 연구는 압전 작동기 기반 초소형 날갯짓 비행체의 날갯짓 운동을 위해, 압전 작동기의 펌핑 운동을 효과적으로 날갯짓 운동으로 변환하는 힌지 메커니즘 제작 기법에 대해 다루었다. 경량화를 위해 탄소섬유/에폭시(Graphite/Epoxy) 프리프레그를 사용하고, 반복적인 제작이 용이하도록 레이저 절단기를 활용하였으며, 힌지부는 얇은 캡톤 필름을 이용해 컴플라이언트(compliant) 메커니즘으로 구성하였다. 제작된 힌지 메커니즘을 압전 유니모프 작동기 PUMPS에 연결하여 동작시켜 본결과, 300V 170Hz 인가 전압에서 $173^{\circ}$의 큰 날갯짓 각을 가짐을 확인하였다.
