Modeling the Friction Boundary Layer of an Entire Brake Pad with an Abstract Cellular Automaton
Lubricants, 2018 The principle energy exchange of a brake system occurs in the tribological boundary layer between the pad and the disc. The associated phenomena are primarily responsible for the dynamics of brake systems.

A Second-Order Dynamic Friction Model Compared to Commercial Stick–Slip Models
Modelling, 2023 Friction has long been an important issue in multibody dynamics. Static friction models apply appropriate regularization techniques to convert the stick inequality and the non-smooth stick–slip transition of Coulomb’s approach into a continuous and ...

Gravitomagnetic dynamical friction [PDF]
Physical Review D, 2017 A supermassive black hole moving through a field of stars will gravitationally scatter the stars, inducing a backreaction force on the black hole known as dynamical friction. In Newtonian gravity, the axisymmetry of the system about the black hole's velocity $\mathbf{v}$ implies that the dynamical friction must be anti-parallel to $\mathbf{v}$. However,

Characterization of Dynamic Friction Factor for FEM Modeling of High Speed Process
Engineering Transactions, 2014 The present study aims to establish through a series of friction tests the trends of the dynamic factor according to sliding speed. A ballistic set-up using an air gun launch is used to measure the friction coefficient for the steel/carbide contact ...

Surgical Endoscopy, 2006 In minimally invasive surgery, force feedback information on tissue manipulation is altered by friction between the instrument and the sealing mechanism of the trocar. It is unknown how the different sealing mechanisms of currently available trocars influence the friction forces.

Dynamical friction for compound bodies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 In the framework of the fluctuation-dissipation approach to dynamical friction, we derive an expression giving the orbital energy exchange experienced by a compound body as it moves interacting with a non homogeneous discrete background. The body is assumed to be composed of particles endowed with a velocity spectrum and with a non homogeneous spatial ...

Optimal control design for robust fuzzy friction compensation in a robot joint [PDF]
, 2009 This paper presents a methodology for the compensation of nonlinear friction in a robot joint structure based on a fuzzy local modeling technique. To enhance the tracking performance of the robot joint, a dynamic model is derived from the local physical ...

Static Friction Phenomena in Granular Materials: Coulomb Law vs. Particle Geometry
, 1993 The static as well as the dynamic behaviour of granular material are determined by dynamic {\it and} static friction. There are well known methods to include static friction in molecular dynamics simulations using scarcely understood forces.
