摘　　要：在灰色系统理论的基础上,将目标响应全压和效率的联合优化转化为关联度的单目标优化。在离心风机的稳健设计中,需要满足高效率、充足的全压等多目标关联性能要求。本文对通风机叶轮中的可控因子进行试验设计,并用流体仿真CFD软件来计算流体三维模型对应的效率和全压目标响应值,对计算的目标响应序列进行关于灰色关联的方差分析,得到各个因子及各个水平对目标域值的影响程度,从而获得因子的最佳参数。案例结果表明,灰色理论、CFD气动计算和方差分析和离心通风机稳健设计,能够促进离心通风机的性能提升。The grey system theory is used to transform the multi-objective optimization into a single objective optimization problem,and taking the relational degree as target function between the target sequences.In the robust design of centrifugal fan,it is usually required to meet a number of targets,such as high efficiency,sufficient total pressure and other quality requirements.In this paper,the experimental design of the controllable factor in the centrifugal fan impeller is carried out,and the target response value of the input parameter for impeller is obtained by using the existing CFD software.The variance analysis of the grey relational degree of the calculated target sequence is carried out,and the influence degree of each level of each factor on the response of the target is obtained,so as to get the best parameter of the factor.The research shows that the application of grey theory used to the robust design of centrifugal fans achieves good results,which indicates that this method is of great applicability in multi-objective robust design.
