Abstract

In this paper, we evaluate structural integrity of the wearable robot by using finite element analysis, which is made of CFRP(Carbon Fiber Reinforced Plastic) composite materials to be lightened. On the basis of the ASTM(American Standard Test Method), mechanical tests of the material are carried out in tensile, compressive and shear test for analytical evaluation. With the tested composite material, the main frame and two femoral frames of the robot is redesigned to satisfy the lightening design requirements. It is verified with the structural analysis that the redesigned frames are good for the part of the wearable robot.

본 논문은 착용형 근력지원 로봇의 경량화를 위하여 CFRP(Carbon Fiber Reinforced Plastic) 복합재료의 적용 설계와 유한요소해석을 이용한 안전성 평가 내용을 기술하였다. 금속재 프레임으로 제작된 착용형 근력지원 로봇에 대하여 탄소섬유 복합소재로 대체하였고, 적용 재료에 대하여 ASTM을 기준으로 인장, 압축 그리고 전단시험을 통하여 해석적 평가를 위한 기계적 물성시험을 수행 하였다. 구조해석 결과를 이용하여 설계된 경량 착용형 근력지원 로봇의 메인 프레임 및 대퇴부 프레임은 경량 설계의 설계요구조건을 만족하였으며 제작된 로봇이 기존 금속재 프레임 대비 경량화 효과를 얻을 수 있음을 확인하였다.
