Abstract

Aiming at the abnormal phenomenon of rail corrugation that generally occurs on the outer rails of large radius curved tracks on a long ramp, the dynamic model of a vehicle-track system was established in the high-incidence section of rail corrugation on the basis of the field measurement.The dynamic characteristics of the leading wheelset-rail system were investigated when the As metro vehicle passing through the high-incidence section of rail corrugation.Then, based on the viewpoint of wheel-rail frictional self-excited vibration, a finite element model of the wheelset-rail system supported by elastic long sleepers in the relevant interval was established.The complex eigenvalue analysis was applied to study the frictional self-excited vibration characteristics of the system.The correlations between the wheel-rail creep characteristics, the frictional self-excited vibration of the wheelset-rail system and the rail corrugation were provided so as to reveal the generation mechanism of the abnormal phenomenon of rail corrugation.Furthermore, the effects of vehicle dynamic parameters and the track support structure parameters on the frictional self-excited vibration of the wheelset-rail system were studied respectively and related methods for suppressing the rail corrugation in the curve interval were proposed.The results indicate that the creep force between the outer wheel of leading wheelset and the outer rail tends to be saturated during the transition of the vehicle form even track to circular curved track in the high-incidence section of rail corrugation.The saturated creep force between the outer wheel and rail easily causes the wheel-rail frictional self-excited vibration, which may induce the abnormal rail corrugation on the outer rail of curved track with a wavelength of 50—60 mm.The study of the suppression method finds that the change of the vehicle dynamic parameters has little effect on the wheel-rail frictional self-excited vibration.Reducing the vertical stiffness and damping of the fastener in a certain range is helpful to suppress the occurrence of the wheel-rail frictional self-excited vibration.When the vertical stiffness of the fastener is 5 MN/m and the vertical damping is 10 000 N•s/m, the occurrence possibility of the wheel-rail frictional self-excited vibration in the section is least.The results provide a references for the suppression of the abnormal rail corrugation in the mountain city metro.
