TL;DR: In this article, a detailed investigation conducted into the mechanism of the polygonal wear of metro train wheels through extensive experiments conducted at the sites is presented, including model tests of a vehicle and its parts and the tracks, the dynamic behaviour test of the vehicle in operation and the observation test of polygonale wear development of the wheels.

TL;DR: In this paper, a rotating flexible wheelset model is developed and integrated into a vehicle/track dynamic model, which considers the effect of the wheelset flexibility and the rotating effect.

TL;DR: In this article, a new wheel-rail contact model was developed for considering the effect of wheel-set bending deformation on wheelrail contact behavior at high speeds, which is suitable for high-speed vehicles.

TL;DR: Wang et al. as mentioned in this paper summarized current research progress covering aerodynamics, catenary-pantograph interaction,dynamics and related issues of carbody, stability analysis, rail-wheel interaction, reliabilityof key components, and mechanisms about noise-generation.

TL;DR: In this paper, the authors developed a numerical model for wheel-rail noise analysis in both time and frequency domains based on vehicle-track coupling dynamics considering the effect of flexible wheelsets and track.
