Open publisher page 1 citations

Abstract

The optimization design and dynamics analysis of the multi-megawatt wind turbines blades are studied in this paper.First,considering the change of circumferential velocity in the actual process of air flow,the aerodynamic shape of the 2 MW wind turbine blades is designed based on the Schmitz theory.Second,the solid model for the blade is established by using the three-dimensional coordinates of each section,which has been calculated by the coordinate transformation of the blade airfoil parameters.Then the solid model is input to the finite element analysis software.Last,the influence of the layer thickness and ply angle on the modal characteristics and aerodynamic load of the blade are analyzed.
