Abstract

In this study, we discussed the weight reducing of 2 MW class of wind turbine rotor shaft by optimizing design method. The optimal design was applied to obtain get an optimized structure and parameters for the base structure using FEA and DOE. The results were verified by comparing the maximum von Mises stresses and maximum volume in the case of the existing design with those in the case of the optimized design. It was shown that the weight of a base structure can be reduced by about 23 %.

2MW급의 풍력 로터 샤프트의 경량화를 위한 최적설계를 수행하였다. 유한요소해석과 실험계획법을 이용하여 경량화를 위한 변수를 도출하였고, 이를 기반으로 샤프트의 치수 최적화를 수행하였다. 최적 설계안과 현재 설계의 발생응력과 중량을 체적을 통해 비교하여 타당성을 검증하였다. 이 과정을 통하여 중량을 현재보다 약 23 % 정도 줄일 수 있었다.
