摘要

中文摘要: 以建立于NACA翼型族厚度分布方程基础上的机翼形水工建筑物多目标水力优化为目标，基于Isight数值优化平台，通过Hicks-Henne型函数实现翼型参数化、多岛遗传算法（MIGA）筛选最优解，构建自动集成与优化体系；选用某小型平原灌区末级矩形渠道机翼形量水槽为算例，根据原型工况及水力参数设定相关约束条件，引入收阻比δ概念，并结合淹没度S构建多目标优化方案，验证优化平台的可靠性与准确性，结果表明，优化方案较初始方案S与δ分别提升10.84%和42.10%。研究结果对机翼形水工建筑物在实际工程中的外形优化与应用提供了一定的参考和建议。

Abstract

Abstract:Taking multi-objective optimization of airfoil-shaped hydraulic structure based on NACA thickness distribution as objective，an optimization model was established based on Isight platform.In this model

airfoil parameterization was realized by Hicks-Henne Shaped function.Parameters were selected and optimized by multi-island genetic algorithm.Taking an airfoil-shaped measuring flume in the final stage of rectangular cannal which set on small plain irrigation area as example

constraint condition was determined by archetype conditions and hydraulic parameters.Multi-objective optimization model was established combining contraction-drag ratio δ and submergence degree S.The reliability and accuracy of Isight platform was verified by optimized results.Results showed that the coefficients δ and S increase by 10.84% and 42.10% compared with the initial structure.Therefore

this research would provide recommendation for optimization of airfoil-shaped hydraulic structure and its application in irrigation system.
