Dynamical friction coefficient maps using a scanning force and friction microscope

Applied Physics A Solids and Surfaces, 1994
A novel method to analyze and to distinguish the non-dissipative component from the dissipative frictional component of the lateral force in a Scanning Force and Friction Microscope (SFFM) is worked out and applied to images acquired on various samples.

The effect of surface roughness on normal restitution coefficient, adhesion force and friction coefficient of the particle-wall collision

Powder Technology, 2020
Abstract The normal restitution coefficient is an important parameter in particle deposition which is widely used in industrial fields. The normal restitution coefficient can be affected by many factors, and a typical factor is the surface roughness. Furthermore, a rough surface will influence the adhesion force and friction coefficient. The adhesion

Friction of a pimpled rugby ball surface: Force and velocity weakening and strengthening of the coefficient of friction

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2012
Friction of rubber is known to behave non-linearly, depending on contact pressure and sliding speed. The surface of a rugby ball made of natural rubber with regular pimples was investigated, and the coefficient of friction between finger skin and rubber surface was determined at normal forces of 0.4–40 N and sliding speeds of 0.001–3.2 m/s.

A new device for simultaneous measurement of friction force, normal force and friction coefficient

Wear, 1975
Abstract To meet the demands for higher accuracy in the measurement of forces in tribological experiments a force transducer has been developed which allows the simultaneous measurement of friction force, normal force, and, via an electronic divider, the friction coefficient. The device consists essentially of four bending rods notched at four points

Study of Friction Coefficient and Friction Force on Magnetic Abrasive Finishing

Materials Science Forum, 2011
In order to enhance grinding efficiency of the magnetic abrasive finishing (MAF) method, we usually use the sinter method or the cementation method to mix the magnetic particles and abrasive particles together. However, the cost is high, and the variety is incomplete.

Forces and coefficient of friction during cylindrical three roller bending

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018
Three roller bending process is one of the processes of forming cylindrical shells, for manufacturing drums, pressure vessels, windmill towers, etc. During the bending process, forces on the rollers must not exceed their bending capacity. Along with operational and material parameters, the forces exerted during bending and power consumption are ...

Effects of Ploughing Forces and Friction Coefficient in Microscale Machining

Journal of Manufacturing Science and Engineering, 2006
This paper discusses the effects of ploughing and friction in microscale machining. The friction coefficient has previously been shown to be sensitive to the geometry of the abrasive particle and the depth of indentation. From a micromachining standpoint, the friction coefficient is modeled to be a function of the tool edge radius and the undeformed ...
