Investigating the Friction Behavior of Turn-Milled High Friction Surface Microstructures under Different Tribological Influence Factors

open access: yesJournal of Manufacturing and Materials Processing, 2022
The coefficient of friction (COF) is an important parameter for mechanical engineers to consider when designing frictional connections. Previous work has shown that a surface microstructuring of the harder friction partner leads to a significant increase

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 ...

Effect of potato contact parameters on seed metering performance using discrete element method

open access: yesSpanish Journal of Agricultural Research, 2022
Aim of study: To study the effect of potato surface with or without sandy loam soil on seed metering performance, we investigated the motion behaviour of the potato seed particles during the seed metering process using a self-designed across-bridge ...

Static and kinetic friction of rapeseed

open access: yesResearch in Agricultural Engineering, 2007
he present paper examines the static and kinetic coefficient of friction of rapeseed. The project utilized two methods of determination of coefficient of friction of rapeseed: according Eurocode 1 (kinetic) in direct shear test and (static) in model silo.

Frictional Anisotropy of 3D-Printed Fault Surfaces

open access: yesFrontiers in Earth Science, 2021
The surface morphology of faults controls the spatial anisotropy of their frictional properties and hence their mechanical stability. Such anisotropy is only rarely studied in seismology models of fault slip, although it might be paramount to understand ...

Measuring the Static Coefficient of Friction of Non-Fluid Contaminants [PDF]

open access: yesProceedings of the Human Factors and Ergonomics Society Annual Meeting, 2019
The purpose of our study was to evaluate whether there are differences between measuring the static coefficient of friction (SCOF) of a non-fluid contaminant when it is directly attached to a tribometer test foot, or “Attached”, versus when it is lying loose on the floor, or “Loose”. The non-fluid materials used in this study included Mylar, Cardboard,

Material and interaction properties of selected grains and oilseeds for modeling discrete particles [PDF]

open access: yes, 2010
Experimental investigations of grain flow can be expensive and time consuming, but computer simulations can reduce the large effort required to evaluate the flow of grain in handling operations.
