摘　　要：针对风力机叶片气动性能与叶尖噪声无法良好兼顾的问题,本文提出翼型气动性能与噪声同步优化设计方法。采用B样条函数表达翼型曲线,利用RFOIL软件计算翼型的气动性能,基于噪声半经验公式(BPM模型)预测翼型的噪声;建立基于气动性能与噪声特性的风力机翼型优化数学模型,利用多目标遗传算法并耦合RFOIL软件及BPM模型编制优化程序,通过不断优化迭代输出Pareto最优解,根据最优解得到新翼型参数,将新翼型命名为WT24-210翼型;将新翼型与常用FFA-W3-211翼型的气动性能进行比较,结果表明:在雷诺数6×10^(6),马赫数0.10的边界条件下,光滑条件和粗糙条件下,新翼型的最大升阻比都比FFA-W3-211翼型有所提高,分别提高6.6%和1.7%;当在6°攻角时,在光滑和粗糙条件下其噪声值则分别降低了0.5 dB和1.2 dB。For the problem that aerodynamic performance and tip noise of wind turbine blades cannot be well balanced,a synchronous optimization design method for airfoil with high aerodynamic performance and low noise was proposed in this paper.The B-spline function was used to express the airfoil curve,and the RFOIL software was selected to calculate the aerodynamic performance of the airfoil.The noise of the airfoil was predicted based on the noise semiempirical formula(BPM model).A mathematical model for wind turbine airfoil optimization was established based on aerodynamic performance and noise characteristics.An optimization program by using multi-objective genetic algorithm coupled with RFOIL software and BPM model was developed.Through continuous optimization iteration,the Pareto optimal solution was output,from which the new airfoil parameters were obtained.A set of optimal solutions was selected to obtain a new airfoil,named WT24-210 airfoil.The results show that under the boundary conditions of Reynolds number of 6×10^(6) and Mach number of 0.10,the maximum lift to drag ratio of the new airfoil is increased by 6.6%and 1.7%respectively,compared with that of FFA-W3-211 airfoil,under the smooth and rough conditions.At the angle of attack of 6°,the noise value is reduced by 0.5 dB and 1.2 dB,respectively,under both smooth and rough conditions.
