This paper focuses on the pervasive issues of environmental vibration,noise,and ballastless track vibration damage during the operation of high-speed railways.It primarily reviews the correlation between ballastless track vibrations and related issues,as well as the frequency domain research methods for ballastless track vibrations.The principles and applications of various frequency domain methods are summarized,and their advantages and limitations are comparatively analyzed to clarify their respective applicability.The results indicate that:(1)ballastless track vibrations are correlated with environmental vibrations,noise,and track vibration damage in terms of spatial location and frequency domain range.(2)ballastless track vibrations play a crucial role in influencing environmental vibrations,noise,and vibration-induced damages such as wheel polygonization,rail corrugation,and fastener clip fractures.(3)frequency domain research methods for ballastless track vibrations can be broadly categorized into those based on periodic track structure theory and those grounded in power flow theory.Both approaches are suitable for investigating the mid-to-high frequency vibration characteristics and related issues of ballastless tracks.
