| 摘 要： | 为提高高超声速飞行器设计的水平,提出一种结合优化设计和灵敏度分析的新设计策略,并将其应用于高超声速乘波飞行器的二维一体化构型的设计.结合实验设计方法、响应面技术和遗传算法构建了一套改进的优化方法,结合设计参数取值域、正交设计和方差分析发展了一种灵敏度分析方法.在优化设计过程中,通过参数化建模、网格自动生成和CFD求解,应用改进的优化方法对飞行器进行了多点多目标设计,得到了Pareto最优前沿面和优化推荐构型.针对推荐构型,应用灵敏度分析方法进行了非设计状态的性能分析,并基于灵敏度分析结果对推荐构型进行了修形设计.

| Abstract: | To improve the design level of Hypersonic Cruise Vehicle,this paper researches the optimal design and sensitivity analysis of 2D waverider.Combining design of experiment,surrogate models and genetic algorithm,this paper develops a modified optimization method,which is applied in the integrated design of hypersonic waverider.Combining parameterized shape generating,grid auto-generation,CFD solver and optimization method,waverider is optimized in muti-objective way.The Pareto front and optimal configuration are obtained.Combining preferences,orthogonal design and variance analysis,this paper builds sensitivity analysis method,which is applied in reviewing the influence of design variables.At last,optimal configuration is modified. |
