[Abstract]:In order to study the bending and torsion coupling effect of the blade of a composite material wind turbine, the blade of the wind turbine is simplified as a symmetrical and nonuniform layer laminate beam. The effect of the coupling region on the bending and torsion coupling effect of the blade is studied by experiment and numerical analysis. The experimental principle and measurement method of the bending and torsion coupling effect of the uniform laminated plate beam are given. The deflection and torsion angle of the symmetrical inhomogeneous laminate beam are measured. Based on the ANSYS software, the finite element model of the symmetrical inhomogeneous laminate beam is set up. The deformation of the beam under the load of the concentrated force is calculated. The results of the finite element numerical analysis and the results of the finite element analysis are given. The experimental results show that the coupling region has an important influence on the deformation behavior of the symmetrical inhomogeneous laminate beam, and a significant bending and torsional coupling effect can be obtained by using the middle coupling zone layer mode.
