摘要
基于多学科优化理论,提出复合材料风力机叶片气动/结构一体化优化设计方法。采用多岛遗传算法,以叶片的气动和结构性能为约束、质量为目标,对复合材料风力机叶片进行优化设计。气动性能分析采用叶素动量理论,考虑叶梢损失和轮毂损失。结构分析采用有限元方法对风机叶片三维参数化CAD模型进行分析。算例结果证明了该方法的有效性,对实际的工程设计有较强的参考价值。
An aerodynamics/structure integrated design method of composite blade of wind turbine was presented based on muhidisciplinary design optimization. Multi-island Genetic Algorithm was used to optimize the mass of composite blade with constrains of aerodynamic and structural performance. A blade element momentum theory （BEM） method was used in aerodynamic analysis considering tip loss and hub loss. 3D parametric CAD model was analyzed with finite element method （FEM）. The results show that the method brings higher efficiency.
