Abstract
Twist-bend coupling is a very important way to reduce the fatigue loads for megawatt blades. This paper studied the twist-bend coupling properties of 5MW wind turbine blades using finite element method. Twist angle, flapwise bending angle and coupling parameter are given for each aspect by applying same loading condition. Simulated results show that material can greatly affect the coupling properties while the influence induced by the structure of blade can be ignored.
