航空宇航薄壁曲面结构中存在大量减重孔、维修孔、冷却孔等孔形设计问题,对于结构的轻量化、性能与寿命具有重要的影响.由于三维曲面上的孔形优化设计必须保证优化过程中孔形曲线始终位于特定曲面结构上,现有工作难以实现设计变量的合理定义与工程数值仿真自动化设计.西北工业大学张卫红教授领导的研究团队长期致力于航空航天轻质结构的优化设计方法研究.博士研究生王丹与其指导教师张卫红教授等研究人员在“三维曲面上
There are a large number of hole-shaped design problems in aerospace thin-walled curved surface structures, such as weight-reducing hole, repair hole and cooling hole, which have an important impact on the weight reduction, performance and life-span of the structure.As the hole- Hole-shaped curve in the process is always located on a specific surface structure, the existing work is difficult to achieve a reasonable definition of design variables and engineering numerical simulation automation design. Northwestern Polytechnical University Professor Zhang Weihong research team led by long-term commitment to the optimal design of lightweight aerospace structure Research Dr. Wang Dan and his tutor Professor Zhang Weihong and other researchers in the ”three-dimensional surface
