Journal of structural engineering (JOSE)Summary: A method to determine static and free vibration responses of wind turbine blade (WTB) is proposed. One dimensional finite element wind turbine blade (1DFEWTB) model is developed using thin-walled beam theory coupled with preComp tool and thhe blade element momentum (BEM) theory and implemented to calculate aerodynamic loading. The 9.2m long WTB is chosen for the study and the effect of different parameters such as aerofoil, twist variation and wind operating speed on the response and on estimated power generated by blade are computed. The results form the 1D model (developed using MATLAB) are in good agreement with that of 3 D Model (developed using ansys and NuMAD) and are found to be efficient, fast and yet accurate for realistic WTB analysis.
