摘　　要：滚动轴承是动车组列车的关键基础零部件,我国动车组高速、长时间持续运行的特点,以及多变的运行环境,使得动车组轴承的工作环境及其内部受力状态较一般轴承更为复杂,这对轴承的设计制造及可靠性提出了更高的要求。为实现我国高速铁路核心技术完全自主化,近年来针对动车组轴承的研究众多。该文首先介绍了动车组轴承的设计制造与工艺,阐述了动车组轴承在服役过程中的典型失效模式、机理及其影响,随后归纳了动车组轴承故障诊断方法与技术,并对轴承可靠性建模与寿命评估方法的研究现状进行论述,最后简要阐述了动车组轴承的可靠性试验研究。通过对动车组轴承及其可靠性研究进展的总结,可为我国轴承的自主设计理论及制造技术提供参考。Rolling bearing is regarded as the key component of high-speed trains.The characteristics of highspeed,long-term and continuous operation of China’s Electric Multiple Units(EMUs),as well as the variable operating environment,make the working environment and internal stress state of EMUs’bearing more complex than those of general bearing,which puts forward higher requirements for the design,manufacture and reliability of bearing.To realize the localization of China's high-speed railway core technology,a number of researches were carried out on the EMUs’bearing in recent years.This paper firstly introduces the design and manufacturing technology of the EMUs’bearing,and discusses the typical in-service failure modes of the EMUs’bearing,as well as the failure mechanisms and effects.Consequently,the fault diagnosis methods of the EMUs’bearing are classified and summarized,and the reliability modeling and life evaluation methods of the EMUs’bearing are reviewed.Finally,the reliability test of the EMUs’bearing is briefly described.This paper summarizes the research of bearing and its reliability for EMU trains,which can provide a reference for the design and manufacturing technology of the bearing of China’s high-speed EMUs.
