Abstract

This work dealt with the design and manufacturing of composite blades of a vertical axis wind turbine system. In this work, aerodynamic and structural designs of sandwich composite blades for a vertical axis wind turbine system were performed. First, the aerodynamic and structural design requirements of the composite blades were investigated. After the structural design was complete, a structural analysis of the wind turbine blades was performed using the finite element analysis method. It was performed with the stress and displacement analysis at the applied load condition. A design modification for the structurally weak part was proposed as a result of the structural analysis. Through another structural analysis, it was confirmed that the final designed blade structure is safe.

본 연구는 수직축 풍력 발전 시스템의 복합재 블레이드에 대한 설계 및 제작 연구이다. 본 연구에서 수직축 풍력 발전용 복합재 블레이드의 공력 및 구조 설계를 수행하였다. 1차적으로 복합재 블레이드의 공력 및 구조 설계 요구 조건이 분석되었다. 구조 설계 이후 유한 요소 해석 기법을 활용하여 풍력 블레이드 구조의 구조 해석이 수행되었다. 적용 하중 조건에서 응력 및 변위 해석이 수행되었다. 단계적 구조 해석을 통해 취약 부위의 개선 설계 방안을 제시하였다. 구조 해석을 통해 최종 설계된 블레이드 구조는 안전한 것으로 확인되었다.
