Abstract: Objective: To reduce the vibration impact of city railway EBB (elastic bearing block) ballastless track on surrounding environment, it is necessary to determine the reasonable range of fastener stiffness and subblock stiffness combinations for the EBB ballastless track, which will enable optimal vibration reduction effects for city railway with EBB ballastless track. Method: Based on vehicletrack coupled dynamics theory, the vibration response timehistory curves of city railway trains passing under different combinations of fastener stiffness and subblock stiffness are analyzed. Furthermore, the frequency response curve and frequency division vibration level curve of EBB track bed plate and those of monolithic track bed plate are obtained. Through comparison and analysis, the reasonable range of fastener stiffness and subblock stiffness in EBB track structure is preliminarily determined. Result & Conclusion: When the subblock stiffness increases, the Z vibration level of EBB track bed plate increases accordingly; when the fastener vertical stiffness increases, the Z vibration level of EBB track bed plate increases accordingly, and the Z vibration level of common monolithic track bed plate also increases slightly. Under the conditions of train operating speed of 160 km/h, fastener stiffness value around 6080 kN/mm and subblock stiffness value around 80110 kN/mm, the EBB track system can achieve good vibration reduction effects, with a maximum vibration reduction value of 7.79 dB.
