The influence of frictional facing thickness on the contact pressure distribution of multi-disc dry clutches [PDF]

open access: yesFME Transactions, 2018
Frictional heat is generated when the clutch starts to engag. As a result of this operation the surface temperature is increased rapidly due to the difference in speed between the driving and driven parts.

Dry friction of microstructured polymer surfaces inspired by snake skin

open access: yesBeilstein Journal of Nanotechnology, 2014
The microstructure investigated in this study was inspired by the anisotropic microornamentation of scales from the ventral body side of the California King Snake (Lampropeltis getula californiae).

Isostaticity at Frictional Jamming

open access: yes, 2013
Amorphous packings of frictionless, spherical particles are isostatic at jamming onset, with the number of constraints (contacts) equal to the number of degrees of freedom.

Experimental Evaluation of Brake Pad Material Propensity to Stick-Slip and Groan Noise Emission

open access: yesLubricants, 2018
Frictional and dynamic responses of brake pad materials, when sliding on brake disc counterfaces, are at the origin of noise, vibration and harshness (NVH) issues such as brake noise emissions.

Soft Finger Model with Adaptive Contact Geometry for Grasping and Manipulation Tasks [PDF]

open access: yes, 2007
This paper presents a method for building analytical contact models for soft fingers. Friction constraints are derived based on general expressions for non-planar contacts of elastic bodies, taking into account the local geometry and structure of the ...

Nonsteady frictional heating on a sliding contact

open access: yesMATEC Web of Conferences, 2018
We consider quasi-static contact problem on frictional heating on a sliding contact of a rotating rigid cylinder and a half-plane. The cylinder is pressed towards the half-plane material. The problem is reduced to solution of a singular integral equation

Evaluation of heat localization behaviour on brake disk rubbing surface (Proposal of reproducing surface temperature by FEM analysis)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Frictional heat is generated on the rubbing surface and various types of thermal localization occur during sliding contact in braking on disk and pad surfaces.
