旋转机械故障诊断研究方法综述

摘要

With the mechanical structure becoming more and more complicated, rotary machinery need to bear long time work. That would increase the possibility of failure and also make the ways in which the machinery can fail became complicated.Because of that,higher level requirement of rotating machinery of fault diagnosis was demanded.The research status and methods of rotating ma-chinery of fault diagnosis at home and from abroad were analyzed,and then,the application of dimensional and non-dimensional index to the rotary machinery was analyzed.It helps to look into the future research direction of the rotating machinery of fault diagnosis and the problems to be solved about it.%随着旋转机械结构越来越复杂,旋转机械需要承受着长时间的工作,发生故障的可能性增大及故障出现形式趋向于复杂化.因此,对旋转机械故障诊断提出更高的要求.本文作者分析了旋转机械故障诊断国内外研究现状及其研究方法,分析有量纲指标和量纲一指标在其上的运用.展望旋转机械故障诊断的研究方向和待解决的问题.
