摘　　要：在梳理、分析国内外机电装备载荷谱外推最新研究成果的基础上,针对机电装备运行过程中的载荷形式及载荷特性,综述了时域载荷外推、雨流域载荷外推(参数雨流外推、非参数雨流外推和雨流矩阵外推)和分位点外推等载荷外推技术的研究进展和对比分析。在大数据的时代背景下,讨论了机电装备载荷谱外推技术的潜在方向与发展趋势。On the basis of combing and analyzing the latest research results of the extrapolation of the load spectrum of electromechanical equipment at home and abroad,this paper summarizes the research progress and comparative analysis of load extrapolation key technologies:time-domain load extrapolation,rainflow load extrapolation(parametric rainflow,non-parametric rainflow,and rainflow matrix extrapolations),and quantile extrapolation,in view of the load form and load characteristics of the electromechanical equipment during operation.In the context of the era of big data,the potential direction and development trend of the load spectrum extrapolation method in electromechanical equipment are discussed.
