摘要
针对气动优化设计问题,基于优化集成软件Model Center结合VB自编程序、CAD、计算流体力学仿真(CFD)软件及多目标遗传算法构建气动协同优化设计、分析平台,进行梯形机翼多目标气动优化、仿真分析研究。论文研究了三维CFD仿真、响应面代理模型(RSM)分别与多目标遗传算法结合的优化方案及其关键技术的解决途径。算例结果表明两种优化方案结果吻合,结合流场分析,表明优化方法的合理,气动优化设计平台有效。
Taking sweptwing as example of aerodynamic optimization, integration framework of aerodynamic was built based on ModelCenter software with VB program, CAD, CFD software and genetic algorithm. Two kinds of optimization projects, Multi-objective Genetic Algorithm associate with three-dimensional CFD and response surface models （RSM） respectively, were used in the optimization process. The result of two projects associating with analysis of flow field demonstrates feasibility and robustness of those projects for aerodynamic optimization design and integration framework.
