Investigation on the Design, Structural and Modal Analysis for Polymer Matrix Composites at 10º and 20º Twist

Abstract: Finite element evaluation of large (over 0.5MW) nominal power Horizontal Axis Wind Turbine (HAWT) is performed using ANSYS in this project. The strategy is based on the combination of an aerodynamic module, which provides the three dimensional pressure distribution on the blades as input data in order to compute both, blade deformation and stress intensity over the blades.This project also determines the natural frequency of the blade using modal analysis. The material used here are polymer-matrix composites, they are Glass/epoxy, Kevlar/epoxy, Carbon/epoxy and E-glass/epoxy. The stress intensity and displacement for different materials are compared and the best is highlighted which increases the life of the blade. This provides future scope for alternative materials for wind turbine blade
