FRICTION COEFFICIENT OF SMOOTH AND ROUGH RECYCLED RUBBER FLOORING TILES [PDF]

open access: yesJournal of the Egyptian Society of Tribology, 2012
The effect of surface roughness on the frictional behaviour of recycled rubber tiles is discussed. Experiments were carried out by the sliding of the bare foot against smooth and rough groups of rubber tiles of different thickness.

A Brake System Coefficient of Friction Estimation Using 3D Friction Maps

open access: yesLubricants, 2022
The coefficient of friction (COF) is one of the core factors in the evaluation of brake system performance. It is challenging to predict the COF, since it is strongly influenced by several parameters such as contact pressure (p), slip rate (v) and ...

FRICTION AND TRIBOELECTRIFICATION OF EPOXY FLOORINGS FILLED BY ALUMINIUM OXIDE NANOPARTICLES [PDF]

open access: yesJournal of the Egyptian Society of Tribology, 2013
In the present experiments, friction coefficient and electrostatic charge of epoxy composites filled by nanoparticles of aluminium oxide (Al2O3) sliding against rubber were investigated to develop proper materials to be used as flooring materials of high

The Effect of Dry Friction upon the Dynamics of a Short Eccentric Rotor: An Analytical and Experimental Study

open access: yesLubricants, 2023
The paper proposes the study of dry friction by means of a short eccentric rotor. The rotor was designed and realised in the laboratory. In an ideal frictionless situation, a rotor actuated by gravity will have an angular velocity which increases ...

Analysis of the Variation of Friction Coefficient of Sandstone Joint in Sliding

open access: yesAdvances in Civil Engineering, 2020
The friction coefficient of rock joints is closely related to the stability of the slope. However, it is difficult to predict the friction coefficient due to the influence of surface roughness and mechanical properties of rocks.

The Coefficient of Friction of Soccer Balls

open access: yesProceedings, 2020
Nine soccer balls were tested for their friction against a leather sheet, using a force plate. An average normal force of 63.6 N was applied and the movement of the ball had an average velocity of 15 mm/s.
