| 摘 要： | 提出了基于多目标寻优的叶轮机械叶栅多学科设计优化算法,方法包括:采用并行多目标差分进化算法作为优化求解器来搜寻叶栅多学科设计优化问题的Paxeto解集,采用非均匀B样条方法对叶片型面进行参数化处理,通过求解Reynolds-Avergaed Navier-Stokes方程评估叶片的气动性能,耦合气动计算得到的叶片表面压力,应用有限元分析方法预测叶片的强度性能.为证明本文方法的实用性,选择叶片的等熵效率和叶片应力为目标函数,完成了NASA Rotor 37转子叶栅的多学科设计优化,结果表明本文提出的多学科设计优化算法具有良好的优化性能.

| Abstract: | Automated multi-objective and multidisciplinary optimization and design of turboma-chinery blades are proposed in this paper.In this method,an algorithm named Multi-objective Differential Evolution(MDE) is used as a solver to find the Pareto solution sets of multidisciplinary design problem.The Non-uniform B-Spline approach is adopted to parameterize the turboma-chinery blade profiles.The aerodynamic performances of design blade candidates are predicted with a three-dimensional Reynolds-Averaged Navier-Stok... |
