Structure optimization method of radial inflow impeller based on design of experiment and support vector machine

  • 摘要: 针对向心叶轮结构优化设计耗时长的难点,研究并采用了2类关键技术:其一是利用试验设计技术从大量的轮盘结构尺寸中挑选出重要尺寸作为优化设计变量,以减小优化问题规模;其二是利用支持向量机技术建立向心叶轮强度及振动分析的代理模型,以缩短分析时间.在以上研究工作的基础上建立了1种快速高效的向心叶轮结构优化设计方法.随后的1个算例表明:优化后的叶轮寿命提高4倍,优化设计时间为传统方法的1/27,具有良好的工程应用前景.
