The effect of frequency of vibration and humidity on the stick–slip amplitude

International Journal of Mechanics and Materials in Design, 2010
This work examines the variation of stick–slip amplitude with the variation of frequency of vibration and relative humidity on a mild steel disc. A pin-on-disc machine, developed by the authors, capable of vibrating the disc at different frequency is used for the experiments.

Vibration and Noise Behaviors During Stick–Slip Friction

Tribology Letters, 2019
Frictional vibration and noise usually cause machining error and noise pollution. Stick–slip plays an important role in generating frictional vibration and noise. This study characterized frictional vibration and noise during the stick–slip of a Si3N4 ceramic/metal friction by using an acoustic emission method.

MECHANICAL STICK-SLIP VIBRATIONS

International Journal of Bifurcation and Chaos, 1995
In this paper we consider the behavior of a two degree-of-freedom mechanical system incorporating static and dynamic friction, assumed to be a decreasing function of the relative sliding velocity. The model consists of two blocks linked by springs, which ride upon a moving belt.

Stick-slip vibrations and chaos

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1990
Abstract Stick-slip vibrations are self-sustained oscillations induced by dry friction. They occur in engineering systems as well as in our everyday life, e.g. the sound of bowed instruments results from stick—slip vibrations of the strings.

Control of Stick-Slip Vibration in Drillstrings with Multiple Frequencies

2020 American Control Conference (ACC), 2020
Torsional vibration is a common phenomenon, known as stick-slip in oil-well drilling, that causes poor drilling performance, downhole tool failure, and bit wear. It is observed that stick-slip vibration- generally occur at multiple frequencies. To help mitigate torsional vibration, a dynamic model of drillstring is first studied where analytical ...

Oscillation pattern of stick–slip vibrations

International Journal of Non-Linear Mechanics, 2009
Abstract This paper studies the stick–slip oscillations of discrete systems interacting with translating energy source through a non-linear smooth friction curve. The stick–slip limit cycle oscillations of a single degree-of-freedom model are examined by means of numerical time-integration and analytical methods.

Stick‐slip in the presence of a normal vibration

Tribotest, 2002
AbstractThis paper presents a dynamic analysis of a contact system subjected to an applied normal vibration. The tangential motion of the system is found to exhibit stick‐slip behaviour dependent on the applied vibration, even in the absence of a difference in static and kinetic friction or a negative gradient in the friction‐velocity relation.

Complimentarity Problems of Stick-Slip Vibrations

14th Biennial Conference on Mechanical Vibration and Noise: Dynamics and Vibration of Time-Varying Systems and Structures, 1993
Abstract Multibody systems with many friction contacts not being decoupled by some force laws afford a special treatment with respect to the uniqueness of the solution after a contact event. This problem can be solved by an optimization techniques including unequality constraints which corresponds exactly to the physical properties of ...

Random Vibration of a Beam with a Stick-slip End Condition

Journal of Sound and Vibration, 1994
Abstract An analysis is presented of the response of a randomly excited beam with an axial stick-slip end condition. The emphasis of the present effort is on the case in which slipping is a relatively rare event so that, while it does not contribute significantly to the system damping, it does have a marked influence on the non-linear behaviour.
