The effect of track alignment irregularity on wheel-rail contact geometry relationship in a turnout zone [PDF]

open access: yesJournal of Modern Transportation, 2012
The irregularity is a key factor affecting the wheel-rail contact geometry relationship. In this paper, we calculated the wheel-rail contact points at typical sections and obtained the longitudinal variation of the wheel-rail geometry relationship with the trace line method.

Reducing the Diameter of Freight Vehicle Wheels – The Suitability of Q/D as a Control for Wheel-Rail Contact Stress [PDF]

open access: yes, 2013
High wheel-rail contact stress is related to rail damage mechanisms such as gross plastic flow. Such high contact stresses are often generated by freight vehicles which have comparatively high axleloads.

A Design Method for Rail Profiles in Switch Panel of Turnout Based on the Contact Stress Analysis

open access: yesShock and Vibration, 2020
Contact stress between wheel and rail is believed to cause damage to the rail. The relationship between the contact stress and the radius of the rail is initially based on the Hertz contact theory.

Estimation of coefficient of friction between flange and rail utilizing vehicle dynamics simulation (Investigation based on roller-rig test with different lubrication condition)

open access: yesNihon Kikai Gakkai ronbunshu, 2021
The coefficient of friction (COF) between the outer rail and the leading-outside wheel flange of a railway bogie running on sharp curved track is an important parameter for the progress of wheel/rail wear and running safety.
