Comparison of friction models applied to a control valve
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Eight different models to represent the effect of friction in control valves are presented: four models based on physical principles and four empirical ones. The physical models, both static and dynamic, have the same ...

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 ...
Stick-slip friction: A Monte Carlo study
The aim of this study is to analyze the underling molecular mechanics of the stick-slip phenomenon in confined thin films, and its dependence on parameters such as sliding velocity, load, time and temperature. The study ...

"Bristle-State" Friction: Modeling Slip Initiation and Transient Frictional Evolution From High-Velocity Earthquake Rupture Experiments
(Frontiers Media, 2020)
Fracture mechanics theory and seismological observations suggest that slip-rate is constantly changing during earthquake rupture, including dramatic acceleration from static conditions to high velocity sliding followed by ...
Influence of ligation method on friction resistance of lingual brackets with different second-order angulations: An in vitro study
Objective: To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with secondorder angulations. Methods: Two conventional lingual brackets for canines ...
Influência da pressão nominal de contato no coeficiente de atrito estático em plano inclinado automatizado
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2013-07-12)
The relative movement among flat surfaces in contact is common for many engineering projects. During the operation of many mechanisms, friction problems are identified as a main obstacle to the successful performance of ...
