Analysis of Static Characteristic of Hydrodynamic Bearing with Different Surface Roughnesses

open access: yesJixie chuandong, 2020
When the working surface roughness of hydrodynamic sliding bearing reaches the same magnitude (micron) as the oil film thickness, the influence of surface roughness on the characteristic parameters of bearing cannot be ignored.

Fabrication of the laser textured nickel surface and its tribological property under the water lubrication

open access: yesAIP Advances, 2019
Friction is one of the main causes of mechanical component failure and material waste. It is known from the friction theory that changing the roughness of the surface of the material can change the friction property of the material.

Surface friction of hydrogels

open access: yesProceedings of the Japan Academy, Series B, 1999
The sliding friction of various kinds of hydrogels has been studied and it was found that the frictional behaviors of the hydrogels do not conform to Amonton's law F=μW, which well describes the friction of solids. The frictional force and its dependencies on the load are quite different depending on the chemical structures of the gels, surface ...

Surface Topography Modelling for Reduced Friction

open access: yesStrojniški vestnik – Journal of Mechanical Engineering, 2011
The aim of the present research was to investigate the possibility to design contact surfaces with reduced friction using surface roughness and topography analysis. For this purpose, different 100Cr6 plate samples with different surface topography were prepared.

Experimental Study of Reciprocating Friction between Rape Stalk and Bionic Nonsmooth Surface Units

open access: yesApplied Bionics and Biomechanics, 2015
Background. China is the largest producer of rape oilseed in the world; however, the mechanization level of rape harvest is relatively low, because rape materials easily adhere to the cleaning screens of combine harvesters, resulting in significant ...

Frictional Properties of a Surface Covered With Soft Metal Surface Film (Surface Topography and Frictional Properties)

open access: yesJournal of Tribology, 1986
The friction between a real engineering surface composed of many micro-asperities and a surface covered with soft metal film is discussed. First, the frictional coefficient shows a remarkable load dependency, when a hard single protuberance with a small radius of curvature is slid on a soft metal surface.

Friction Coefficient Tests for Designs of Belt Conveyor Drive Systems

open access: yesApplied Sciences
In conveyor belt drive pulleys and intermediate belt drives, the power transferred from the drive system to the belt increases together with the increasing friction coefficient between the belt surface and the pulley surface, or between the surface of ...

Effect of Time-varying Friction Factors on the Contact Fatigue Life of Gears

open access: yesJixie chuandong, 2023
The tooth surface friction has an important impact on the tooth surface contact stress and the tooth surface contact fatigue life. In the estimation of the contact fatigue life of the tooth surface, the influence of the friction force of the tooth ...
