Analysis of the Adhesive-bonded Joint Stress in a MW Segmented Assembly Wind Turbine Blade

摘要

The stress distribution of adhesive-bonded joint in a MW segmented assembly wind turbine blade under static loading is analysed using finite element method (FEM). It is shown that the maximum principal stress causes the adhesive layer destruction away from the loading end of the sleeve layer. Numerically, the interface layer destruction trend of the adhesive-bonded joint is investigated, and the influence of maximum principal stress distribution by altering the sleeve length is investigated.
