Abstract

In this paper, the structural design for composite blade was performed and full scale structural test was conducted to verify the structural design and integrity of composite blade. Firstly, FE analysis was performed using commercial software ABAQUS under conditions of rated wind speed and Case H in IEC 61400-2. Lay-up sequence and ply thickness were designed based on FE results. And to verify the structural design, full scale structural test was conducted according to IEC 61400-2 under identical loading conditions of FE analysis. Finally, the force-deflection and local strain behavior of composite blade were evaluated.

소형풍력발전시스템의 복합재 블레이드에 대한 실규모 구조시험 및 이를 모사한 구조해석을 통하여 설계 타당성을 검증하였다. 먼저 IEC 61400-2 에 규정된 설계 요구조건의 만족을 위하여 정격 풍속 및 IEC 61400-2 Case H 의 최악 조건에 대한 구조해석을 수행하고 이를 통하여 적층 순서 및 적층 두께를 결정하였다. 또한 이러한 구조해석의 타당성 검증을 위하여 IEC 61400-23 에 따라 구조해석과 동일한 하중조건에서의 실규모 구조시험을 실시하였다. 이러한 실규모 구조시험을 통한 구한 블레이드의 하중-변위 선도 및 표면의 변형률 특성을 이용하여 블레이드의 구조적 안전성을 평가하였다.
