Abstract

Abstract:

In view of the rail corrugation problem commonly existing in subway small radius curves, the influence of wheel-rail mechanical parameters on rail corrugation is studied from the perspective of wheel-rail wear. A single wheel-set simulation model integrating wheel-rail dynamic model, wheel-rail rolling contact mechanics model and Archard material wear model is established using MATLAB/Simulink. The simulation results show that the larger the radius of the curve, the less likely the rail corrugation occurrs. The result is consistent with the frequent corrugation of the small radius curve, which proves the correctness of the model. Subsequently, the model is used to further analyze the influence of vehicle load and curve super-high on the wave grinding.

Key words: subway, wave wear, dynamics simulation, curved track, wear quantification, analysis of influencing factors
