Abstract: When wind turbine blade becomes bigger and bigger, we need more optimization of blade design which requires fast generation of FEM model. The parameterized method could generate blade model quickly and accurately, which is explored in this paper. From aerodynamic design, the aerofoil data, blade shape layout, component positioning data, material performance, lamination plan and etc information are parameterized. After research, we can calculate the nodes, elements and lay-out data required by FEM model. Finally, the formatted data for FEM software could be generated automatically.

Key words: wind turbine blade, parameterized model, FEM analysis, automatic mesh
