Friction‐Induced Vibration of Artificial Hip Joints

GAMM-Mitteilungen, 2009
AbstractA 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 of an elastic slider on a vibrating disc

International Journal of Mechanical Sciences, 1999
The 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.

VIBRATIONS AND FRICTION-INDUCED INSTABILITY IN DISCS

The Shock and Vibration Digest, 1998
The 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.

Friction induced vibrations in shift gearboxes

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2014
AbstractIn 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.

Friction Induced Vibration: Brake Moan

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">Techniques have been developed to model friction induced vibration and these were applied to the brake moan of a vehicle. A vehicle system model and the MSC/NASTRAN solutions for geometric nonlinear and complex modes were modified by DMAP for friction input.

Frictionally Induced Vibrations

2010
From a system dynamics point of view, technical systems with friction are non-linear dissipative open systems. Even if it is possible for a system to be in a state of steady motion, it can only practically take place if it is stable relative to small disturbances. Otherwise, the perturbations intensify, resulting in a periodic or chaotic vibration.

Friction induced vibration

2011
Frictional vibrations have been induced in a system having an elastically suspended,and viscously damped slider loaded onto a surface driven-at constant velocity. Exact mathematical analysis-of the system reveals a unique value of the driven surface velocity, above which frictional vibrations of the slider cannot exist.

The Measurement of Friction and Friction-Induced Vibration

Journal of Lubrication Technology, 1970
The 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.

A study of friction induced vibration

2011
Frictional vibrations, which occur when two solid bodies are rubbed together, are analyzed mathematically and observed experimentally. In the mathematical analysis, the non-linear differential equation of motion during the slip period is derived making use of the experimental friction-velocity curve.

Friction-induced vibrations of reciprocating contacts

Tribology International, 1995
The tangential and normal oscillations for three reciprocating and sliding pairs of different materials are experimentally obtained at different normal loads and reciprocating frequencies. The magnitude and phase shift of the transfer function have been measured to correlate the normal and tangential induced oscillations.
