In contrast to other third-body layers–such as water, oil, sand, and leaves–iron oxides exert
a constant influence on the friction and wear of wheel–rail contact. However, studies that …

Friction management and control of adhesion at the wheel/rail interface is vital for an
efficient and cost effective railway network. The understanding of how the friction …

Two models for wheel-rail rolling contact that are based on the half-space assumption are
compared in this paper: Hertz and the non-Hertzian method implemented in the computer …

The wheel-rail adhesion characteristics are very important for the safe and stable operation
of vehicles. This railway-specific problem has been studied since the beginning of the …

The objective of this study was to investigate the influence of the surface topography on the
tribological behavior of the wheel/rail contact. Four different groove orientations forming the …

In this study, the effect of natural third body layers on the coefficient of friction and contact
forces is evaluated using the Virginia Tech-Federal Railroad Administration (VT-FRA) roller …

Knowledge of wheel–rail interaction is crucial to wheel and rail maintenance. In this
interaction, some of the worn-off material is transformed into airborne particles. Although …

A wheel/rail system is an open system, where the operating environment factors, such as
atmospheric humidity, temperature, and oxidation behavior, are subject to change. This …

The contact area and pressure distribution in a wheel/rail contact is essential information
required in any fatigue or wear calculations to determine design life, re-grinding, and …
