LINEAR STATIC ANALYSIS OF WIND TURBINE BLADE USING FE MODELLING.

The requirements for improved stiffness, reliability, fatigue life and increased efficiency involves challenges of developing innovative design solutions. The present work mainly focus on the design of wind turbine blade where the analytical and FEM analysis approach was implemented to analyze baseline design. Initially static analysis was performed to obtain total deformation, strain and the stress of wind turbine blade. Three Dimensional model was created using CATIA and FE software ANSYS was used for discretization and analysis to obtain expected solution. The results were obtained through linear static analysis in terms of Total deformation while Minimum principal stress, Max Principal stress were found to be nearly equal for both CFRP and Aluminium alloy model. Finally on comparing the results of CFRP with AL it was observed that the overall weight of the wind turbine blade was optimized.
