摘　　要：基于多学科优化软件Isight和计算流体力学软件NUMECA的平台,对试验设计、近似模型和优化算法相结合的优化策略进行集成,并通过程序语言Python进行界面开发,搭建了适用于核主泵水力模型的自动优化设计平台。利用该平台,以课题组自主设计的水力性能优良的核主泵模型泵作为研究对象,以CFD计算结果为基础,建立了反映设计变量与目标函数之间关系的近似模型,对核主泵叶轮几何形状及其与导叶入口距离之间的交互效应进行研究;并采用多岛遗传算法进行优化,获得了水力性能更加优良的水力模型。结果证明了初步构建的核主泵集成优化平台的实用性与采用优化策略针对过流部件进行优化的可行性与合理性。A multi-disciplinary optimization software Isight and CFD simulation software NUMECA were used to integrate the optimization strategy,numerical experimental design,approximation model and global optimization algorithm into one design platform.The user interface was created by Python.The automatic optimization design platform suitable for a hydraulic model of nuclear reactor coolant pump has been established.Based on the model pump obtained by our research group in preliminary studies,the automatic optimization design platform was used to establish the approximation model,and it can reflect the relationship between design variables and the objective function.Then the impeller and impeller-guide vane interaction was studied.Multi-island genetic algorithm was used.A pump model with improved hydraulic performance was obtained.The results show that the initially built integrated optimization platform is of applicability.The feasibility of the optimization strategy has also been verified.
