Friction Correction of Austenite Flow Stress Curves Determined under Axisymmetric Compression Conditions
(Springer, 2019-03)
The experimental flow stress curves of structural steels obtained from axisymmetric compression tests conducted under hot-working conditions very often include the frictional effects present at the tool/specimen interface. ...
Two-State GMS-Based Friction Model for Precise Control Applications
(Springer, 2016-05)
The capability of a model to represent the complex friction behavior is particularly important for systems where friction has a major impact on motion precision. In this work a GMS-based model is proposed which would require ...
Numerical simulation of the lubricant performance
(Elsevier Science Sa, 2008-03)
Due to the high pressures that are involved in tube hydroforming processes, high values of the friction forces are developed and, therefore, lubricants are usually employed to increase the formability of the workpiece. ...
Frictional dynamics of viscoelastic solids driven on a rough surface
(American Physical Society, 2015-07)
We study the effect of viscoelastic dynamics on the frictional properties of a (mean-field) spring-block system pulled on a rough surface by an external drive. When the drive moves at constant velocity V, two dynamical ...
Quantum friction between graphene sheets
(American Physical Society, 2017-03-16)
We study the Casimir friction phenomenon in a system consisting of two flat, infinite, and parallel graphene sheets, which are coupled to the vacuum electromagnetic (EM) field. Those couplings are implemented, in the ...
A simplified model for friction compensation in precise feed drives
(Inderscience Enterprises, 2018-11)
Friction is a complex phenomenon with negative effects on the precision of positioning systems. In this work, a single-state friction model for control purposes, aimed to simplify the implementation of control algorithms ...
Modelling an Inertia Wheel Pendulum Benchmark
(Taylor & Francis, 2005-09)
In this paper, modelling and parameter identification of an inertia wheel pendulum benchmark is considered. This is an underactuated mechanical system useful for teaching and research. Attention is focused on deriving a ...
Energy dissipation by friction for sliding blocks subjected to near-fault seismic base motion
(Techno-Press, 2021-05)
The objective of this study was to determine friction ratios that maximize energy dissipation on a seismic damper. The aforementioned friction damper basically consists of mass blocks that are able to slide on a flat ...
Analytical, numerical and experimental studies on the Semi-Active Friction Tendon
(Elsevier, 2017-09)
For controlling vibrations, a Semi-Active Friction Tendon (SAFT), which consists of a semi-active friction damper and an auxiliary spring that are linked to the structure by a cable, is studied experimentally, numerically ...
Kinetic Monte Carlo theory of sliding friction
(American Physical Society, 2009-10-15)
The sliding friction as a function of scanning velocity at the nanometer scale was simulated based on a modified one-dimensional Tomlinson model. Monte Carlo theory was exploited to describe the thermally activated hopping ...
