Modeling of braking thermal effect for wheel-rail contact parameters

Proceedings of the Institution of mechanical engineers. Part F, journal of rail and rapid transit, 2020
The Hertzian contact parameters are evaluated by taking into account the increase in temperature of the wheel due to braking under a steady mechanical loading.

The Optimization on Tread Profile Based on Wheel-Rail Match

Applied Mechanics and Materials, 2014
The matching status of wheel/rail affect the driving stability and safety directly. It could improve the dynamic behaviors by optimizing the matching status of wheel/rail. Taking the wheel rim tread named LMa as an object, the wheel diameter curve method was used to optimize the profile of tread LMa. Then the dynamic behaviors of the optimized profile (

Hardness matching of rail/wheel steels for high-speed-train based on wear rate and rolling contact fatigue performance

Materials Research Express, 2019
Hardness matching between rail and wheel is important for the safe and economic operation of high speed train. In this work, various hardness of 39.5, 36.8, 33.4, 30.5, 28.1 HRC were achieved in the wheel steels tempered at 748, 773, 793, 813, 833 K ...

Multi-objective optimisation of wheel-rail adhesion for high-speed trains with aerodynamic lift wings

Vehicle System Dynamics
A high-speed train with aerodynamic lift wings (aero-wings) is designed to improve train speed and mitigate energy consumption. Nevertheless, the impact of aero-wings on wheel-rail adhesion and safety remains uncertain.
