On the Robustness of Instabilities in Friction–Induced Vibration
Journal of Vibration and Acoustics, 2013Friction-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 rail vibrations
AIP Conference Proceedings, 2012A 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.

Friction Induced Brake Vibrations
Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001Abstract 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.

Modelling and control of friction-induced vibrations [PDF]
Mathematical and Computer Modelling of Dynamical Systems, 2005 Friction-induced vibrations in technical applications are usually unwanted, as they create noise, diminish accuracy and increase wear. This article intends to give insight into basic excitation mechanisms of friction-induced vibrations and to show possible ways of avoidance.

Friction‐Induced Vibration of Artificial Hip Joints
GAMM-Mitteilungen, 2009AbstractA hip replacement system is analysed with respect to its susceptibility to friction induced vibrations under laboratory conditions and in a pseudo‐in vivo setup. The method of complex eigenvalue extraction within the framework of finite‐element modelling and analysis is used to identify the geometric properties and system parameters that might ...

Friction-induced vibration and noise on a brake system
2013 IEEE International Conference on Information and Automation (ICIA), 2013The 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.

Friction-induced vibration of an elastic slider on a vibrating disc
International Journal of Mechanical Sciences, 1999The authors consider stick-slip vibrations of an elastic disc. The investigation is motivated by the fact that there exists a whole class of mechanical systems with discs rotating relative to stationary parts, such as car brake discs, clutches, saws, computer discs and so on.

Friction induced vibrations in shift gearboxes
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2014AbstractIn shift gearboxes, audible vibrations can arise during the process of clutch engagement. Measurements show an unstable axial motion of the gear unit input shaft. In order to explain this effect, an approach which establishes the interaction of the slipping clutch and the gearing is proposed.

VIBRATIONS AND FRICTION-INDUCED INSTABILITY IN DISCS
The Shock and Vibration Digest, 1998The simple shape and common occurrence of disks as machine elements belies a complexity of behavior that can be an important factor in the improvement of modern machine performance. The purpose of this paper is to give a thorough account of the understanding gained from recent research investigations into the dynamics of disks.

The Measurement of Friction and Friction-Induced Vibration
Journal of Lubrication Technology, 1970The design, development, and application of a pin-on-disk tribometer for the measurement of friction and friction-induced vibration is described. Careful isolation techniques eliminated many of the errors in measurement which are associated with vibration arising from the apparatus or the surroundings.
