摘　　要：风力机结构优化对提高能源转换效率至关重要。为低成本探究叶片数量(n)、半径(R)、展弦比(μ)和安装角(β)四个结构参数对垂直轴风力机气动性能的影响,采用基于田口方法的正交试验设计和改进的加性模型,确定了使风力机功率输出最大化的最优设计参数,并进行了CFD数值验证研究。结果表明,利用田口法结合改进的加性模型,能够准确确定最优的参数组合及各因素对其气动性能的影响程度。分析得出在n=3、R=2.5 m、μ=8、β=-3°时,风力机性能最强;而在n=5、R=1.0 m、μ=5、β=0°时性能最弱。与最差构型相比,最优构型的平均功率系数提升了66.12%;四个因素对垂直轴风力机效率的影响程度大小为R>n>β>μ。The optimization of wind turbine structure is of paramount importance for enhancing energy conversion efficiency.To explore the influence of four structural parameters—number of blades(n),radius(R),aspect ratio(μ),and installation angle(β)—on the aerodynamic performance of vertical-axis wind turbines at a low cost,an orthogonal experimental design based on the Taguchi method and a modified additive model were employed.This approach determined the optimal design parameters for maximizing the wind turbine's power output and conducted CFD numerical validation studies.The results indicate that the combination of the Taguchi method and the modified additive model can accurately determine the optimal parameter combination and assess the extent of influence each factor has on aerodynamic performance.The analysis indicates that the wind turbine exhibits the strongest performance at n=3,R=2.5 m,μ=8,β=−3°,and the weakest performance at n=5,R=1.0 m,μ=5,β=0°.The average power coefficient of the optimal configuration is 66.12%greater than that of the worst configuration.Furthermore,the magnitude of the influence of each factor on the efficiency of the vertical axis wind turbine is R>n>β>μ.
