摘要
基于二阶响应面模型,结合气动性能的精确分析和结构重量的概念分析,采用自适应退火算法和序列二次规划算法相结合的优化策略,对高速民用运输机机翼进行多学科设计优化,以寻找机翼气动布局最优和起飞总重最轻的折衷点。初步分析了机翼的气动和结构性能,并有效地改善了其性能。
An optimization strategy based on quadratic response surface model is proposed in this paper,combining the exact analysis of aerodynamic performances and concept analysis of structural weight.With the integration of adaptive simulated annealing algorithm and sequential quadratic programming method,the multi-disciplinary design optimization of a high-speed transport wing is processed to search for a compromised point of the best aerodynamic layout and the minimum take-off gross weight.Aerodynamic and structural performances are preliminarily analyzed and effectively improved.
