摘要
风力机叶片性能随铺层参数的不同而不同.本文依据一阶响应曲面设计原理,设计了铺层参数不同水平的方案.以整体结构性能最优为目标,铺层参数为自变量,叶片强度、刚度为响应变量,采用Minitab中的田口设计法进行试验设计,模拟了叶片的静态结构性能;经多元线性回归构建了铺层参数与Tsai-wu失效因子、最大位移之间的一阶数学模型,进行了显著性检验;分析了铺层参数对叶片性能的影响,验证了方法的可行性和有效性.
The property of wind turbine blade varies with its laminating parameters.Schemes with different laminating parameters were constructed according to the design principle of the first-order response surface.With the optimal overall performance as the goal,laminating parameter as independent variables,and the strength and stiffness of the blade as dependent variables,Taguchi method in Minitab was used to design the experiment.The static strength and stiffness of the blade was simulated.The first-order mathematical model showing the relationship between laminating parameter,Tsai-wu failure factor,and maximum displacement was established by multiple linear regression and significance test was conducted.The effect of laminating parameters on blade structure property was analyzed.The correctness and effectiveness of the method was verified.
