Curve squeal is an intense tonal noise occurring when a rail vehicle negotiates a sharp
curve. The phenomenon can be considered to be chaotic, with a widely differing likelihood …

Friction is the bond linking the tangential and normal forces at the wheel-rail interface.
Modeling friction is the precondition for the wheel-rail adhesion calculation. In this work, the …

The evolution of wheel-rail dynamic interaction of a high-speed railway vehicle is essential
for the simulation of wheel-rail rolling contact damage under low adhesion conditions. The …

Curve squeal is commonly attributed to self-excited vibrations of the railway wheel, which
arise due to a large lateral creepage of the wheel tyre on the top of the rail during curving …

This research evaluates the efficiency of five noise mitigation measures including rubber
floating slab track, straight noise barrier, track acoustic absorber, track-side noise barrier …

The interaction between wheel and rail is the predominant source of noise emission from
railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail …

In the field of railway simulation, it is a general assumption to consider the coefficient of
friction as a known and constant value. This hypothesis is clearly not correct as friction is a …

Purpose–The purpose of this paper is to develop a numerical approach to solve the
transient rolling contact problem with the consideration of velocity dependent friction …

In this paper the influence of a velocity-dependent friction law on the interactions inside the
contact patch between a rolling wheel and a rail is presented, assuming that the quasi-static …

Squeal of rail-bound vehicles emitted in tight curves is characterized by high sound pressure
levels at pure medium and high frequencies. Many models have been proposed in the …
