Friction induced rail vibrations

AIP Conference Proceedings, 2012
A model of rail, considered as multiple supported beam, subjected on friction induced vibration is studied in this work using FEM. The model is presented as continuous system and the mass and elastic properties of a real object are taken into account. The friction forces are nonlinear functions of the relative velocity during slipping.

Experimental analysis of friction-induced vibrations at the finger contact surface

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2010
When a finger moves to scan the surface of an object, the sliding contact generates vibrations that propagate in the finger skin and transmit the information about the object characteristics to mechanoreceptors. Mechanoreceptors convert vibrations into electric impulses sent to the brain. In this context, by appropriate experiments, a

Friction-Induced Vibration

Journal of Lubrication Technology, 1967
Friction-induced vibration has been studied in a system consisting of an elastically suspended, damped slider which is loaded against a surface moving at a constant velocity. Exact analysis reveals a critical velocity which limits the incidence of vibration.

Bifurcation and Chaos in Friction-Induced Vibration

Design Engineering, 2002
Friction-induced vibration is a phenomenon that has received extensive study by the dynamics community. This is because of the important industrial relevance and the evere-volving development of new friction models. In this paper, we report the result of bifurcation study of a single-degree-of-freedom mechanical oscillator sliding over a surface.

On the Robustness of Instabilities in Friction–Induced Vibration

Journal of Vibration and Acoustics, 2013
Friction-induced vibration and the noise or wear it causes are everlasting problems in the design of dynamical mechanical systems. The most common way to analyze friction-induced vibration is to determine the borders of linear stability. In that framework, the present study focuses on robustness concepts of systems prone to friction-induced vibration ...

Friction Induced Brake Vibrations

Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract This paper deals with friction induced brake vibrations showing frequencies above 1 kHz and a narrow bandwidth. This phenomenon is usually called ‘brake squeal’. After analyzing squeal excitation mechanisms, a rigid body brake model displaying the main features of a floating caliper disc brake is presented.

Friction-induced vibration and noise on a brake system

2013 IEEE International Conference on Information and Automation (ICIA), 2013
The experimental set-up of a disc brake system are established. The LuGre friction model is adopted to determine the friction force between the disc and the pad. The nonlinear dynamic behavior of the brake pad with non-internal condition is discussed, also the shrill frictional noise signals are investigated.
