摘要
采用图形变形法分析了固体火箭发动机设计优化模型中各设计变量对目标函数和约束的影响程度,探索了可行设计空间,通过显示优化结果点附近设计空间形态定性分析了优化结果鲁棒性。结果表明,图形变形法处理固体火箭发动机设计优化多变量分析及显示问题简单、直观,易于工程应用。
Graph Morphing is presented to analyze the importance, or sensitivity, of each variable to objective and constraints in optimization model for solid rocket motor design. It is also used to explore the feasible design space and to analyze the robustness of the optimization result. Engineering application proves that Graph Morphing is simple and intuitive to deal with multivariate analysis and visualization problem and have bright future in solid rocket motor design optimization.
