- In order to study the effects of sectional warping to bend-twist coupling characteristics for box spar of wind turbine blade, section stiffness of different regions are calculated with weather considering warping effect or not, the results show that warping effects differently in different part of the blade and the length width ratio and thickness of spar cap are two factors that determine impact degree of warping. Section stiffness of a 5MW blade box spar considering warping effect are calculated, bend-twist coupling coefficients are got. The results show that warping effect bend-twist coupling coefficient of box spar greatly and it should be considered when research the blade bend-twist coupling.
