| Abstract: | The analytical and finite element methods are used to solve the stress and strength ratios of the three basic deformations of the members under tension,bending and torsion,and the results are compared and analyzed.Using the APDL language of ANSYS,the finite element model of the composite blade of 2MW horizontal axis wind turbine is established,and the modal and static characteristics of the blade are analyzed.The results show that geometric modeling,delamination definition,constraint and load definition are all correct using finite element analysis.The numerical results of natural frequency,stress and displacement are reliable.When gravity acts,the maximum displacement occurs at the tip of the blade,and the maximum stress is located at the junction of the airfoil and the blade root.Under wind load,the blades with vertical upward,downward and horizontal directions are studied,respectively.The maximum displacement and stress values change,the former occurs at the tip,and the latter are located in the middle. |
