Abstract

Blade is one of the key components in wind turbine, which is needed to be enough stiffness, strength and stability. Loading calculation is significant for the blade strength analysis. In this paper, a three-dimension model of wind turbine blade is set up by CATIA software and the blade shape parameters are obtained. Based on blade element momentum (BEM) theory, the load acted on the blade in normal operation is analyzed and calculated. Moreover, stress analysis of blade is carried out by finite element numerical analysis and stress distribution is obtained. At last, Strength checking for wind turbine blade is also achieved. The results of the analysis are reference for wind turbine blade loads research.
