Abstract：In order to study the influence on the strength of the wind turbine' blade by the ply schedule，the finite element model of the blade was established，and the strength indexes of the blade were gotten at various ply schedules by FEM. At last，the ply schedule was optimized by DOE. The research result shows that ±45° ply laminate has a greater effect on the strength of the blade than 0° ply laminate dose；these two kinds of laminates have coupling effect on the strength of the blade；the ply schedule derived from DOE meets the blade strength requirements.
Key words： DOE； wind turbine； blade strength
