Evaluation of Different Contact Assumptions in the Analysis of Friction-Induced Vibrations Using Dynamic Substructuring

open access: yesMachines, 2022
Dynamic substructuring methods are initially developed for time-invariant systems to evaluate the dynamic behavior of a complex structure by coupling the component substructures.

Tactile perception by friction induced vibrations [PDF]

open access: yesTribology International, 2011
When a finger moves to scan the surface of an object (haptic sensing), the sliding contact generates vibrations that propagate in the finger skin activating the receptors (mechanoreceptors) located in the skin, allowing the brain to identify objects and perceive information about their properties.

Modelling and control of friction-induced vibrations [PDF]

open access: yesMathematical 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.

Acoustic Energy Transfer by Friction Induced Vibrations

open access: yesProcedia Engineering, 2017
Abstract Friction-induced vibrations are often investigated for their unwanted effects, such as surface wear and dynamic instabilities. This article focuses on the exploitation of friction-induced vibrations to transfer the energy between different acoustic fields by an interface under frictional contact.

Feature Recognition on Friction Induced Vibration of Water-Lubricated Bearing under Low Speed and Heavy Load

open access: yesJournal of Marine Science and Engineering, 2023
Under low speed and heavy load operating conditions, the marine water-lubricated bearing (WLB) is often in a mixed lubrication state. This leads to abnormal friction-induced vibrations and noise in underwater vehicles.

Eliminating Stick-Slip Vibrations in Drill-Strings with a Dual-Loop Control Strategy Optimised by the CRO-SL Algorithm

open access: yesMathematics, 2021
Friction-induced stick-slip vibrations are one of the major causes for down-hole drill-string failures. Consequently, several nonlinear models and control approaches have been proposed to solve this problem.

Effect of Track Support Structures on Friction-Induced Vibrations of Wheelset-Track Systems

open access: yesShock and Vibration, 2023
The aim of the present investigation is to study the effect of track support structures on the metro 5th to 8th-order out-of-round (OOR) wheel caused by friction-induced vibrations. Three finite element models of metro-leading wheelset-track systems with

Tribological characteristics and mechanism of nitrile butadiene rubber coated with typical liquid lubricants

open access: yesPolymer Testing, 2022
When marine stern shafts operate under low speed and heavy load conditions, the metal shaft and water-lubricated bearing will be in a state of boundary lubrication or even dry friction.

Quasi-harmonic friction induced vibration [PDF]

open access: yesWear, 1971
A theoretical and experimental investigation of quasi-harmonic friction-induced vibration is reported. The vibration is of near-sinusoidal form and is solely governed by dynamic friction forces. However, the friction-velocity curve must be of a particular shape for the vibration to occur.

On the Use of Linear and Nonlinear Controls for Mechanical Systems Subjected to Friction-Induced Vibration

open access: yesApplied Sciences, 2020
Friction-Induced Vibration and noisE (FIVE) is still a complex and nonlinear physical phenomenon which is characterized by the appearance of instabilities and self-sustained vibrations.
