飞机总体参数优化的可视化技术

摘要: 为了提高飞机总体设计参数优化建模的效率和增强最优解选择的合理性，将可视化技术融入飞机总体参数优化。采用MATLAB编程技术开发了一个优化建模的图形界面，使得优化建模过程大为简化；以散点图形式监控优化计算过程，有助于判断优化模型定义和优化算法选择的合理性；由目标空间的散点图、反映所有参数的平行坐标图和反映约束边界的界限线图所组成的优化结果可视化，有助于直观了解目标空间、参数相关性、变量可行域及所确定的最优解与各约束边界的距离。

Abstract: The visualization techniques are merged into aircraft conceptual design optimization to improve the efficiency of optimization formulation and enhance the rationality of the solution selection. The definition of optimization formulation is implemented with a MATLAB programming graphical interface, which greatly simplifies the optimization formulation. The scatter diagrams are used to monitor the optimization process, which helps one judge the rationality of the optimization formulation and algorithms. The visualization interface for optimization results consists of three graphs-a scatter diagram for objective space, a parallel coordinate for the parameters and a plot for constraint boundary, which contributes to an intuitive understanding of the object space, the parameter correlation, the feasible domain of design space and the distance between the optimal solution and the constraint boundary.
