摘　　要：为进一步发挥复合材料铺层参数的可设计性潜力,提出融合离散材料优化法与遗传算法的叶片铺层角度优化方法。构建以细观单元铺层角度为设计变量、刚度最大为目标函数、应力最小为约束条件的叶片细观纤维铺层角度优化数学模型。应用Python语言编写算法求解程序,并与Abaqus软件交互进行求解,得到叶片各单元各层优化的铺层角度、铺层顺序和各铺层纤维的厚度。以1.5 MW叶片为例,优化后叶片的最大位移和Tsai-Wu失效因子明显减小,性能显著提升,验证了该方法与算法的有效性和可行性。In order to further develop the design potential of ply parameters of composite layer,an optimization method of ply angle for wind turbine blade is proposed,which combines DMO method with genetic algorithm.The topology optimization mathematical model for micro ply angle of blade is established,which takes the element ply angle as design variable,the maximum stiffness as the objective function and the minimum stress as the constraint condition.Python language is used to write the algorithm program and solve the problem interacted with Abaqus software.Finally the optimized ply angle of each unit and layer are obtained.Taking 1.5 MW blade as an example,the maximum displacement and Tsai-Wu failure factor of optimized blade are reduced,and the properties are significantly improved.The effectiveness and feasibility of the method are verified.
