Railways are an environmentally friendly means of transport well suited to modern society.
However, noise and vibration are key obstacles to further development of the railway …

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 …

This is the first part of a series of three papers dealing with curve squeal of urban rolling
stock such as metros and trams. After a brief review of the present state of the art, the key …

Environmental requirements for railway operations will become tighter in the future. In
particular, annoyance due to railway noise has to be taken carefully into account in 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 …

Curve squeal is one of the most annoying types of noise caused by the railway system. It
usually occurs when a train or tram is running around tight curves. Although this …

Wheel squeal vibration and noise amplitude under the effects of mode coupling and rising
and falling creep behavior is investigated and predicted using an efficient analytical model …

Field application of friction modifiers on the top of rail has been shown to effectively curb
squeal and reduce lateral forces, but performance can be variable, according to other …

Wheel squeal noise is a common problem that occurs in railway systems especially on
curved tracks. These tonal noises are usually found at high frequency, typically over 1 kHz …

This work is an in-depth analysis of frictional phenomena including macroscopic stick–slip
and mode coupling instabilities, which can occur at different scales ranging from …
