摘要
科学的试验设计方法能够显著提高学术研究和工业生产的质量和效率。以空气动力学试验设计为背景,介绍了现代试验设计方法的研究进展:总结了风洞试验中单因子试验设计方法 OFAT(One Fact at A Time)和现代试验设计方法MDOE(Modern Design Of Experiments)在试验目的、组织策略和试验结果 3个方面的区别,分析了现代试验设计方法的优势;从试验样本选取、模型建立和结果分析3个方面梳理了现代试验设计方法的现状,着重介绍了试验设计中的填充设计和序贯设计两大类试验样本选取方法;对所述试验设计方法进行了算例演示;讨论了当前存在的一些关键科学问题和未来研究方向。
The scientific experimental design method can significantly improve the quality and efficiency of scientific research and industrial production. This paper introduces and summarizes the research progress of modern test design methods. Firstly, this paper summarizes the differences between OFAT(One Fact at A Time) method and MDOE(Modern Design Of Experiments) method in the wind tunnel test in three aspects: the test purpose, organization strategy and test results, and analyzes the advantages of MDOE method. Secondly, it summarizes the status quo of the MDOE method in three aspects: the experimental design, model establishment and result analysis. Then we demonstrate the experimental design method with standard functions and aerodynamic examples. Finally, some key scientific problems and future research directions are discussed.
