The Effect of Polish Maintenance on Static Coefficient of Friction [PDF]
, 2004 The static coefficient of friction (μs) of polishes, measured by the James machine and ASTM D2047, provides a measure of the inherent slip resistance of the polish film. When in use, polish films are invariably modified by traffic and routine maintenance procedures that could, theoretically, change the inherent slip resistance of the film.

Study of the static coefficient of friction of fishing cordage on a friction gear drum [PDF]
Journal of Friction and Wear, 2010 Fiction interaction of fishing cordage and a friction gear drum under the preliminary displacement on the contact arc by 40–720° is studied. In all experiments, similar pressure of the cordage on the drum surface is ensured. Formulas for the static coefficient of friction are obtained for any angle of the contact arc.

An identification method for static and dynamic friction coefficients
2007 International Conference on Control, Automation and Systems, 2007This paper deals with the identification of static and dynamic friction coefficients. An approach based on limit cycles properties once a regulated mechanical system is brought to oscillations is proposed. This leads to an explicit formulation in the regulator parameters on one part, and the oscillation amplitude and period on the other part.

Static and dynamic coefficient of friction in friction pairs of disc-pad brakes
Bulletin of Kharkov National Automobile and Highway University, 2022Problem This scientific article is devoted to the value of static and dynamic coefficients of friction of disc-pad brakes. The issue of disc-pad brake wear is very acute because the safety of using the machine itself depends on its reliable operation. Therefore, the relevance of the chosen topic cannot be doubted. Goal.

The Static Coefficient of Friction and the Area of Contact
Proceedings of the Physical Society. Section B, 1950An apparatus for measuring the static coefficient of friction has been designed in which the forces tending to disturb the contact area are minimized and which further enables the contact area to be viewed throughout the experiment. Application of a tangential load, less than that required to give limiting friction, has been shown to give rise to a ...

Coefficients of Friction: Static Versus Dynamic
2020 Joint Rail Conference, 2020Abstract This paper deals with the problem of static and dynamic (or kinetic) friction, namely the coefficients of friction for the two states. The coefficient of static friction is well known, and its theory and practice are commonly accepted by the academia and the industry.

Coefficients of static friction under statically and dynamically applied loads
Wear, 1961Abstract The coefficient of static friction under static loads with normal pressures of about 10,000 p.s.i. and under dynamically applied loads ranging from 10,000 to 20,000 p.s.i. were determined. The test apparatus was so arranged that dynamically applied normal and tangential loads are applied simultaneously. Results are given for combinations of

Static coefficients of friction for polyethylenes
Polymer Engineering & Science, 1966AbstractThe static coefficients of friction of solid polyolefins against metal surfaces has been determined as functions of pressure, temperature, and metal surface finish. The polymers studied were a low debsity (branched) polyethylene, a high density copolymer, and a high density (linear) polyethylene homocopolymer, and a high density (linear ...

An identification method for static and coulomb friction coefficients
International Journal of Control, Automation and Systems, 2009This paper deals with the identification of static and Coulomb friction coefficients. An approach based on limit cycles properties once the mechanical system is brought to oscillations is proposed. This leads to an explicit formulation in the regulator parameters on one part, and the oscillation amplitude and period on the other part.
