Static behavior analysis of disc spring considering variable static friction coefficient
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021The object of this fundamental research will be to reveal the effects of variable coefficient of static friction on the static behavior of disc spring. On account of the complex relationship between friction and normal pressure, based on contact mechanics and fractal theory, a model for predicting variable coefficient of static friction of 3 D fractal

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.

Static coefficient of rolling friction under heating
Journal of Friction and Wear, 2013The effect of heating, the normal load, and the radii of the members in contact on the static coefficient of rolling friction is considered. The design of a new apparatus for measuring the parameters of rolling friction over an inclined plane at elevated temperatures is presented. A need to specify the effect of the type of the materials in contact, as

Measurement of static friction coefficient between flat surfaces
Wear, 1996Abstract An experimental device, called the centrifugal friction apparatus (CFA), was developed which is capable of measuring the static coefficient of friction, μ, between flat surfaces with very low normal forces. Experiments were performed with the CFA using the polished surface of n-type arsenic doped silicon wafers to investigate static ...

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

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.

Determination of the static friction coefficient from circular motion
Physics Education, 2014This paper describes a physics laboratory exercise for determining the coefficient of static friction between two surfaces. The circular motion of a coin placed on the surface of a rotating turntable has been studied. For this purpose, the motion is recorded with a high-speed digital video camera recording at 240 frames s−1, and the videos are analyzed
