基于多学科优化设计方法的航空电子设备应用研究

Multidisciplinary design optimization of airborne electronic equipment

复杂工程系统的设计往往涉及多门学科,多学科设计优化(MDO)方法是一类求解复杂系统设计优化问题的方法,是解决航空电子设备设计等复杂工程系统问题的有效手段。航空电子设备系统包含大量的学科和子系统,因此在设计过程中需要充分考虑各学科间的耦合效应。针对这一问题,提出了改进的单极优化方法为优化策略,以iSIGHT为平台构建了理想的设计环境。通过对电子设备中的典型结构印制板级模块进行了实例分析,验证了该优化设计方法集成复杂设计问题的可行性。

The design of highly complex engineering systems often involves several different disciplines. The methods of multidisciplinary design optimization（MDO）provide the framework for solving design optimization of complex engineering systems,it is regarded as an effective and prospective solution to complex engineering systems such as airborne electronic equipment system,which contents large number of disciplinary and subsystem,the coupling affections between the disciplinary must be considered in the procedure of design, h improved the Simultaneous Analysis and Design method,builded the appropriate design environment. And the basic structure of the electronic equipment PCB level module is optimized as an example. The results showed that the vibration and thermal performances improved obviously,testify the feasible of this optimization method.
