摘　　要：本文采用多目标遗传算法结合近似模型方法,对离心压气机叶轮优化设计程中叶片各个设计参数的变化对于叶轮气动与强度性能的影响进行了研究,更深刻地了解各个参数分别对叶轮气动和强度性能的影响程度,并在此基础上采用可行性解的选择策略来寻求优化设计点,优化后的结果能够满足叶轮气动与强度性能的要求,表明该方法具有一定的工程实用价值。The paper reports the investigation of changes of aerodynamic and structural performance yielded by the variation of the blade design parameters by combination of Multi-objective Genetic Algorithm（GA） with the approximate model method.Based on the deep understanding of the impacts of blade design parameters on the aerodynamic and structural performance,optimal design point is searched by feasible design selection strategy and the optimized impeller aerodynamic and strength performance meet the design requirements,and this indicates that the method has some practical value in engineering.
