Abstract

This study analyzes the fabric skin of a wind turbine blade. The fabric skin is a membrane structure that was analyzed using a static Fluid Structure Interaction (FSI) method. For this study the blade of large 5 MW wind turbine was selected. In order to examine the validity of the analysis, a variety of reference data were used. Before conducting static FSI analysis, a Computational Fluid Dynamics (CFD) analysis and modal analysis were done. Then interaction analysis was conducted. FSI analysis was done with imported Aerodynamic data that resulted from the CFD analysis. The resulting observations about the membrane structure, inherent tensions, deformation of the final structure, and aerodynamic forces caused by deformation are reported.

본 논문에서는 박막구조물 형태를 가진 풍력발전기 블레이드 패브릭스킨의 유체-구조연성해석을 수행하였다. 풍력발전기 블레이드는 5MW급의 중대형 풍력발전기로 선정하여 분석하였으며, 해석의 타당성을 높이기 위하여 다양한 참고문헌을 이용한 검증을 마쳤다. 본 해석에 앞서서, CFD해석과 모달해석을 나누어서 해석을 수행한 후 연성해석 진행하였다. CFD해석에서 나온 공기력 데이터를 장력으로 유지되는 박막구조물인 패브릭스킨에 적용시켜서 최종 구조물의 변형과 변형된 구조물로 인한 공기력의 변화를 확인하였다.
