Effect of fractal disorder on static friction in the Tomlinson model [PDF]

open access: green, 2010
We propose a modified version of the Tomlinson model for static friction between two chains of beads. We introduce disorder in terms of vacancies in the chain, and distribute the remaining beads in a scale invariant way. For this we utilize a generalized

On the Normal Force and Static Friction Acting on a Rolling Ball Actuated by Internal Point Masses [PDF]

open access: green, 2019
The goal of this paper is to investigate the normal and tangential forces acting at the point of contact between a horizontal surface and a rolling ball actuated by internal point masses moving in the ball's frame of reference.

Relationship between contact size and static friction: An approach for rigid crystalline surfaces [PDF]

open access: diamondFriction, 2020
Relationship between contact size (A) and static friction (f) has been studied for rigid crystalline systems. We built a series of systems with two identical surfaces but different orientations and investigated the effects of the size and shape of the ...

Behavior of Friction in Pneumatic Cylinders with Different Relative Humidity

open access: yesTribology in Industry, 2020
Friction directly affects the motion quality and performance of a pneumatic cylinder system. The frictional behavior of pneumatic cylinder depends on pressure, velocity, diameter, lubrication, and working environment, etc.

Motion analysis of passive dynamic walking with a rigorously constraint model: A necessary condition for maintaining period-1 gait

open access: yesBiomimetic Intelligence and Robotics, 2022
The friction force is an important environmental factor that influences dynamic walking. While most of the related works simply assume static friction or Coulomb friction, we use the LuGre friction, which accounts for both static and dynamic effects, to ...

Aging of the frictional properties induced by temperature variations [PDF]

open access: yes, 2010
The dry frictional contact between two solid surfaces is well-known to obey Coulomb friction laws. In particular, the static friction force resisting the relative lateral (tangential) motion of solid surfaces, initially at rest, is known to be ...
