Viscous damping exciting friction-induced vibration in pin-on-disk systems
Results in Engineering, 2021 When engineers add damping to a vibrating system, they typically expect that this will result in a more stable system. However, a few rather complex examples are known that show the opposite trend: situations in which damping generates friction-induced ...

Effect of Normal Contact Vibration on Nano-Scale Friction
Lubricants, 2019 In this work, we investigate the effect of contact vibration on the friction of sliding single asperity contacts of different adhesion strength over a wide range of load and vibration amplitude.

Investigation of Piezoelectric Energy Harvesting via Nonlinear Friction-Induced Vibration
Shock and Vibration, 2020 In this work, piezoelectric energy harvesting (PEH) performance via friction-induced vibration (FIV) is studied numerically. A nonlinear two-degree-of-freedom friction system (mass-on-belt) with piezoelectric elements, which simultaneously considers the ...

Tactile perception by friction induced vibrations [PDF]
Tribology 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.

Dynamic modeling and analysis of wear in spatial hard-on-hard couple hip replacements using multibody systems methodologies [PDF]
, 2015 Wear plays a key role in primary failure of artificial hip articulations. Thus, the main goal of this work is to investigate the influence of friction-induced vibration on the predicted wear of hard hip arthroplasties.

Advances in Mechanical Engineering, 2014 This paper presents friction-induced vibration (FIV) caused by combined mode-coupling and negative damping effects in a simple FIV model. In doing so, a new four-degree-of-freedom linear model which consists of a slider and a block is proposed and then ...

Acoustic Energy Transfer by Friction Induced Vibrations
Procedia 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.

Tectonic tremor as friction-induced inertial vibration
Earth and Planetary Science Letters, 2021 Abstract Slow slip events are often accompanied by tremor but how tremor is generated is yet elusive. In this study, we test the possibility that it is an inertial vibration. In the case of a single-degree-of-freedom spring and slider system with mass per unit area M, governed by rate-and-state friction with effective normal stress σ ...
