摘　　要：压气机叶片的复杂三维构型及薄壁结构导致其加工难度极大,在加工制造过程中叶片几何偏差的不确定性问题十分突出。随着压气机的气动负荷不断攀升、几何尺寸不断缩减,其工作环境及内部流动特征愈加恶劣和复杂。苛刻的工作环境放大了加工偏差的不确定性影响,这导致同批出厂的压气机气动性能分散度大以及服役过程中性能衰减剧烈的问题频发,带来性能不达标甚至故障问题。为此,近年来国内外针对压气机叶片加工偏差的不确定性量化问题已经开展了大量的研究工作。本文从压气机叶片加工偏差的几何建模、概率模型表征、不确定性量化方法及不确定性影响等方面综述了本领域的研究进展,总结了压气机叶片加工偏差不确定性量化面临的关键问题及研究展望。The complex three-dimensional configuration and thin-walled structure of compressor blades lead to great difficulty in their manufacturing,and uncertainty of blade geometric deviation is very prominent in the machining process.As the aerodynamic loading of the compressor continues to rise and the geometric size continues to decrease,its working environment and internal flow characteristics become worse and more complex.The harsh working environment amplifies the influence of machining uncertainty.This leads to the high dispersion of the aerodynamic performance for the same batch of compressors and the frequent occurrence of severe performance degradation in service,resulting in substandard performance and even failure problems.In recent years,a lot of research work has been carried out on uncertainty quantification of compressor blade machining deviation at home and abroad.In this paper,the research progress in this field is reviewed in terms of geometric modeling,probabilistic model characterization,uncertainty quantification method,and uncertainty effect.Finally,the key problems and research prospects of uncertainty quantification on compressor blade machining deviation are summarized.
