| 摘 要： | 针对机翼结构的几何优化问题,提出了一种基于两相法的几何优化设计新方法。采用参数化命令流文件进行有限元建模,利用复合形法进行位置优化,利用MSC/NASTRAN进行尺寸优化,并将尺寸优化结果传递给复合形法作为复合形法进行操作的依据。算例表明,本文所提方法可行,所得结果可信度高。

| Abstract: | This paper presents a novel algorithm,which aims at the solution of geometrical optimization for aircraft wing.In the algorithm,the finite element model was develop by the parameters command flow.The complexmethod is used to optimize the position design variables and MSC/NASTRAN SOL200 used to optimize the sizing design variables.then the results of sizing optimization are transferred to complex-method as the basis of complex-method operation in geometrical optimization.The given example shows that the present method is dependability and feasible. |
