Characteristics Analysis

The stress characteristics on a composite wind turbine blade are analyzed by using a finite element method. The whole stress level of the spar cap and the blade root is higher than that of the shear web and the airfoil plate, so the spar cap and the blade root are the main force-supporting parts. If the stress concentration point on the interface corner between the blade root and the shear web is neglected, the stress of the spar cap is higher than that of the blade root, and its maximum stress and mean stress are 211 MPa and 180 MPa respectively. The maximum stress of the blade is only 34.8% of the tensile stress of the glass-fiber/epoxy composites. It indicates that the laminate structural design of the blade is inclined to be safety.

Abstract: Nowadays wind turbine is used widely in many countries as power plant. When the wind turbine blade rotates there will be aerodynamic forces acting on the blade such as drag, lift, weight and centrifugal forces. When designing wind turbine blade it is necessary to test whether the blade can withstand the aerodynamic forces or not. Stress analysis is a feature that can predict stress acting on construction. Nowadays there are many stress analysis softwares that can be used to predict stress. In this research the stress analysis will be used by using autodesk inventor.The research purposes are to find the stress acting on the wind turbine blade and to get the maximum stress location.

The development process of a glass-fabric composite wind turbine blade is presented. A finite element model is constructed for the design and stress analysis of the wind blade. The wind blade parts were fabricated using the vacuum-bag molding technique. The assembling process of the wind blade is described in detail. The wind blade was tested to validate the suitability of the design. The finite element method is used to predict the failure wind loads of the wind blade.
