On Railway Wheel Squeal : 2nd Report, Mechanism of Specific Squeal Frequency
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1983 The mechanism of specific squeal frequency was investigated by an apparatus with a steel rod and a thin steel disk. Squeals of higher modes occur in rods with smaller sectional areas and squeals of lower modes occur in large rods. Squeal is generated at specific contact positions on a rod. From the theoretical results, it was found that a squeal of the

A nonlinear FE model for wheel/rail curve squeal in the time-domain including acoustic predictions
, 2021 Squeal noise of rail-bound vehicles frequently occurs in curves with a small radius and is a major nuisance for transport users and local residents. For the quantification of squeal intensity, a complete vibro-acoustic analysis is developed in this paper.

Friction influence on brake squeal in disc and drum brakes using complex eigenvalue analysis [PDF]
Revista Brasileira de Ensino de FísicaBrake noise, is a complex issue in automotive and industrial systems caused by friction-induced vibrations between the brake pad and disc. This noise impacts vehicle performance, accelerates component wear, and diminishes consumer satisfaction.

Friction-Induced Vibration of a Railway Wheelset-Track System and Its Effect on Rail Corrugation
Lubricants, 2020 In the present study, the effect of the radius of railway curved tracks on the slip of a wheel on a rail is studied. A 3D finite-element model of a wheelset-track system is established when the creep force between the wheel and rail is saturated.

A case study of railway curve squeal radiated from both the outer and inner wheel
Applied AcousticsThis case study is presented after observations were made that partially contrast the prevailing picture of railway curve squeal given in the literature. These are observations with significance both for modelling and condition monitoring.

Experimental analysis on squeal modal instability
, 2006 International audienceIn this paper, an experimental analysis performed on a simplified brake apparatus is presented. Brake squeal is a major concern in braking design. During past years a common approach for squeal prediction was the complex eigenvalues

Experimental investigation on brake squeal unpredictability: role of the friction noise
Tribology InternationalDynamic contact instabilities represent a common issue in brake industry, causing noise and passenger dissat-isfaction. Past works identified mode coupling as the cause of brake squeal, but the conditions for its occurrence are still not fully understood,

Analysis on Aircraft Brake Squeal Problem Based on Finite Element Method
International Journal of Aerospace Engineering, 2017 Brake squeal phenomenon is a problem that has been long studied using multiple methods and theories. Finite Element Method (FEM) has been applied to the study of brake squeal problem. First, a disc brake model has been established.
