摘要/Abstract

摘要： 转子不对中是旋转机械最常见的故障之一。不对中常引起整机振动加剧、轴承磨损、转静子碰摩等故障，严重时将造成灾难性事故。航空发动机转子系统由于结构复杂、工作温差大、多支点弹性支承，更容易造成滚动轴承支承不对中、联轴器不对中、动态不对中等不对中故障。虽然航空发动机不对中问题严重，但这方面的研究却相对缺乏。本文针对航空发动机转子系统的结构特点，首先论述了滚动轴承不对中、联轴器不对中、航空发动机转子不对中3种不对中故障的研究现状；其次，讨论了不对中转子系统非线性动力学特性及不对中故障定量分析方面的研究成果。最后，对航空发动机双转子系统不对中研究的发展趋势进行了展望。

Abstract: Misalignment is one of most common problems for creating vibration in rotating machinery. Dynamic forces introduced by misalignment can result in serious oscillation of the whole machine, the bearing abrasion, and the rub-impact between rotor and stator, causing catastrophic accidents in severe conditions. Aero-engine rotor system is very likely to cause misalignment because of its complex construction, large difference of operating temperature, and elastic multi-support. Despite its severity, the study of misalignment of aero-engine rotor is inadequate. Based on the structural characteristics of aero-engine rotor system, this paper reviews the literature related to misalignment of aero-engine rotor system. First, this paper reviews the research status in the effects of misalignment on roller bearings, effects of misalignment on couplings, and effects of misalignment on aero-engine rotor. Second, it reviews the latest research hotspots of misalignment of rotor system, including the effects of misalignment on nonlinear dynamics characteristics of rotor system and quantitative analysis of misaligned rotor system. Finally, the research development of misalignment of aero-engine is prospected.

Key words: misalignment of bearing, misalignment of coupling, misalignment of aero-engine rotor, quantitative analysis, aero-engine rotor system, rotor dynamics
