friction self-excited vibration - Opis:
- In order to study the cause of rail corrugation in the tangential braking section near the metro entrance, a transient rolling contact model of three-dimensional solid wheelset-track was established by using the finite element software ABAQUS, and the corrugation phenomenon was analyzed in the time-domain and frequency-domain based on the field measurement. The results show that the unstable friction self-excited vibration of the wheelset-track system is the fundamental cause of rail corrugation in the measured section, and it is precisely because of the “saturated-unsaturated” periodic characteristic of the wheel-rail creep force that ultimately promotes the formation of rail corrugation.
