The Influence and Suppression of Nonlinear Friction
Advanced Materials Research, 2013Direct at NC machine tool feed system, the article analyzed the influence of the nonlinear friction at each motion joint, and points out that the nonlinear friction are the main factors that influence the positioning accuracy of the feed system. The article have discussed the methods for effectively compensation and controlling of the nonlinear ...

The influence of boundary layers on friction
Wear, 1979The influence of boundary layers on friction was investigated using a Bartel lubrimeter. Boundary layers have only a limited life and are re-formed in the contact area. A minimum specific pressure is required to deposit a solid lubricant film. The addition of MoS2 lowers friction and frictional temperature.

Water on ice; influence on friction
Journal of Physics D: Applied Physics, 1983The dynamic friction between polyethylene and a mixture of crushed ice and small amounts of a very dilute solution of H2SO4 in water was measured at temperature from 0 degrees C to -20 degrees C. The liquid has only a moderate 'lubricating' effect which indicates that the generally low friction between polyethylene and ice and snow cannot be explained ...

The influence of contamination on metallic friction
Wear, 1986Abstract A study of accidents in 12 major urban railways over the last ten years has shown that most of the 316 incidents were due to insufficient adhesion. For that reason adhesion research has a special significance: this is especially true of the effects of air contamination from combustion in households and factories as well as from road and air ...

Modelling the influence of velocity on wet friction-element friction in clutches
Industrial Lubrication and Tribology, 2018Purpose This study aims to establish a friction coefficient model relative to the rotation speed of a wet clutch engagement, which can predict friction coefficient under different stages of slipping velocity and different load pressures. In particular, the model has been improved by accounting the speed effect for the perdition of wet friction-element

The influence of friction on the accuracy of bending
2002In manufacturing of working parts, by metal forming there are number of various methods, owing to sorts and largeness of parts as well as demands for form and accuracy that cause different procedures and ways of bending process. Elastic part of deformation causes aberration of form and accuracy in bending.
