| 摘 要： | 大功率电子设备的应用，使得以F-22为代表的先进战斗机电子设备舱的冷却系统面临高热负荷和大热流密度问题。针对先进战斗机的电子设备舱冷却系统的设计优化问题，分析比较了传统设计优化方法与多学科设计优化方法的结构体系及特点。其中传统设计优化方法选用整体优化方法和串行优化方法，多学科设计优化方法选用协同优化和并行子空间优化两种典型方法。通过MATLAB软件及ISIGHT软件平台，对上述优化方法进行仿真，分析仿真结果表明，多学科设计优化方法在解决多变量复杂系统的优化设计问题时，有相对计算量小的优越性。

| Abstract: | With the increase of electronic equipment power, the electronic equipment cooling system of the advanced fighter aircraft like F-22 fighter is facing some problems such as increasing heat flux density and heat load. To solve the optimization of the cooling system of an advanced fighter aircraft＇ s electronic equipment, traditional optimization methods which include global optimization and serial optimization, and Multidisciplinary Design Optimization which include collaborative optimization and concurrent subspace optimization methods are analyzed. By using ISIGHT software and MATLAB software, the optimization results are calculated. The results indicate that Multidisciplinary Design Optimization method has superiority of calculation in solving the design optimization of the complex system with multivariable. |
