Abstract In Chinese metro lines, severe rail corrugations in Cologne-egg fasteners sections occur not only on tight curved tracks, but also on tangential tracks. Based on the viewpoint of friction-coupling self-excited vibration causing rail corrugation, the rail corrugation on a tangential track supported by Cologne-egg fasteners is studied in this paper. An elastic vibration model of a wheel-rail system is established. Both the complex eigenvalue analysis and the transient dynamic analysis are performed to study the stability and the dynamic performance of the wheel-rail system. The simulation results show that the rail corrugation of wavelength 40-50mm on a tangential track supported by Cologne-egg fasteners easily occurs when the creep force is saturated. When the Cologne-egg fasteners characterized by smaller stiffness value are replaced with the DTVI2 fasteners characterized by larger stiffness value, the rail corrugation disappears. Therefore, an appropriate stiffness value of fasteners can suppress the rail corrugation on a tangential track, but the conclusion is not applicable on a tight curved track.
