基于ANSYS二次开发的风力机叶片结构优化
Structural optimization of the wind turbine blade combining the ANSYS secondary development
摘要
Abstract
In view of the 850 kW wind turbine blade, the materials of the layer were changed and the layout was re-designed. Using the thickness of the materials, the location of the webs and the width of the girders as the design variables, the minimum blade mass as the objective function, the optimized mathematical model of the blade was found. The composite material parametric blade model was built by MATLAB and ANSYS, and the optimized process was realized by the modified particle swarm optimization ( PSO) . The ultimate load of every section was solved by BLADED which is based on the blade element momentum theory. The increasing load was applied to every part of the blade and the strained condition of the blade could be described more realistically. The results showed that the blade mass decreased by 12.58%based on the keeping the intensity of the blade and the distance of the tip than the initial blade.关键词
