摘要
本文实现了叶型自动优化设计平台搭建,优化算法为遗传算法,基于成熟造型程序进行流线面造型,叶型采用中弧线叠加叶厚分布的形式.中弧线斜率和厚度分布分别采用三段和两段三阶贝塞尔曲线进行拟合。流场评价工具为MISES软件。对遗传算法引入并行模块,改进后计算速度显著提升。编制了多目标优化函数,通过算例验证了其合理性。
Automatic optimization and design is achieved,optimization algorithm is genetic algorithm.The airfoil is built on streamline surface based on a mature code.The airfoil is combined with camber line and thickness distribution.Tangent of Camber line is fitted with 3- section cubic Bezier line and thickness distribution is fitted with 2- section Bezier line.The flow field is evaluated by MISES.After a parallel mode is inserted into the GA code the calculation velocity is improved considerably.The multi-Objective optimization function is formed and is validated by an example.
