气动和结构多学科设计优化的需求和流程研究

Research of Requirement and Workflow in Multidisciplinary Design Optimization of Aerodynamic and Structure

文中简要介绍了气动和结构耦合问题、多学科设计优化特点和iSIGHT多学科综合设计环境,对多学科设计优化的集成需求、工作流程及其应用进行了研究;在iSIGHT集成框架下,以简单翼为例,实现了三维几何建模软件、气动计算分析软件、结构强度计算分析软件和iSIGHT之间设计过程和数据流的集成。

In this paper,the coupling between aerodynamic and structure dynamic,the characters of multidisciplinary de- sign optimization(MDO)and iSIGHT integration frame are introduced.The integration requirements of MDO,work flow and application are researched.Based on the iSIGHT integration frame,using the simple swing for example,this paper implement the integration of design process and data flow between 3D geometry modeling software,aerodynamic software,structure intensity software and iSIGHT software.
