Abstract

A typical phenomenon of rail corrugation found in metros is still difficult to be solved, in which it generally arises when the curve radius is quite small, whereas it rarely occurs when the curve radius is larger or on a straight track. The phenomenon is studied from the perspective of the effect of track curve radius on rail corrugation in the present paper. According to the theoretical model of friction-induced oscillation causing rail corrugation, different finite element models of tracks of a multiple-wheelset-track system with curve radius from 200 m to 800 m are established. Both the dynamic analysis and the complex eigenvalue analysis are applied to study the saturation of the creep force and the stability of the wheelset-track system. According to the relationships between the creep forces and friction-induced oscillations, the typical behavior of rail corrugation observed in field tests can be explained.
