THE EFFECTS OF WIND TURBINE BLADE TRAILING EDGE MODELING WAY ON BUCKLING

Abstract

Abstract: Buckling of trailing edge is one of the main failure modes of wind turbine blades. In this paper, the finite element method is used to study the difference of buckling in different modeling methods, including, the slope of trailing edge core, trailing edge UD staggered layer, and adhesive modeling method. The results indicate that the trailing edge adhesive may be defined as a solid or shell element (equivalent to a small web). The slope of trailing edge core can be simulated by no less than 3 steps, and the trailing edge UD of each staggered layer can be appropriately simplified.

Key words: wind turbine blade, finite element modeling, buckling, the core slope in the trailing edge, trailing edge UD, adhesive, composites
