Abstract： Vibration performanceofrail vehicles is acrucial factor inensuring operationalsafety，enhancing ride comfort，and prolonging component service life.With the rapid development of high-speed railways and urban rail transit systems，continuous increases in train speeds， increasingly complex track environments，and growing demands for inteligent maintenance have brought both challenges and oportunities to vibration performance maintenance technologies.This paper systematically reviewed the latest research progress and future development trends in this field from five key perspectives： vibration performance evaluation standards，vibration performance design and optimization， vibration performance operation and maintenance， vibration performance degradation prediction，and technological advances inremaining useful life assessment.The study indicates that future vibration performance maintenance will place greater emphasis on preventive strategies.Through model prediction and big data analytics，it willachieve fault early warning and proactive intervention，therebyestablishing a safer，smarter，moreeconomical，and more eficient safetyassurance system forrail transit.This approach wil not only improve operational reliability but also provide significant support for the sustainable development of
rail transportation systems.
Key words： rail vehicles; vibration performance; performance maintenance and safeguarding; performance degradation prognosis
