Surface roughness and dry friction
Physical Review E, 2012Persson's multiscale contact mechanics theory combined with a multiscale Brillouin-Prandtl-Tomlinson model is used to show that on the basis of these models "dry friction" [i.e., kinetic friction that remains at exceedingly small velocities (but still above the creep range) close to its value at higher velocities] should almost always occur for self ...

Nonlinear Oscillations in a System with Dry Friction
International Applied Mechanics, 2005In the paper a case when the right-hand part of motion equations is discontinuous is considered. Attraction in the stagnation zone only ensures the existence of a periodical oscillation mode. Sufficient stability conditions are established for periodic solution of nonlinear system with dry friction.

Dry-Friction Oscillator with an Elastic Stop
Mechanics of Solids, 2021The work considers an oscillator with two degrees of freedom excited by dry friction. The system consists of two masses connected by linear springs. The second mass is in contact with a driving belt moving at a constant velocity and can collide with an elastic stop. Coulomb friction forces act between the mass and the belt.

Dry friction plays an important role in the dynamic behaviour of mechanical systems. Mechanical systems can come to rest in a finite time due to the presence of dry friction. Moreover, dry friction is also responsible for stick-slip vibrations, which occur for instance in brakes, wheel-rail contact and bowed instruments such as violins.

PERFORMANCE OF AN AUTOMATIC BALL BALANCER WITH DRY FRICTION
International Journal of Bifurcation and Chaos, 2005In many industrial applications imbalance is a major cause for unwanted vibrations. One way to compensate for an unknown imbalance is the implementation of an automatic ball balancer. Oil-lubricated automatic ball balancers are applied in hand-held tools and washers.

In Chap. 12 we studied sliding dynamics for lubricated surfaces. We have emphasized several times that most “real” surfaces are lubricated, e.g., by a layer of grease, even if no lubrication fluid has been intentionally added to the system. Nevertheless, in some cases the increase of the static friction force with the time of stationary contact, due to

Tribometer for Dry Friction Measurement
Volume 7B: 17th Biennial Conference on Mechanical Vibration and Noise, 1999Abstract This paper deals with the measurement of dry friction. A tribometer was developed in order to identify both the sticking and the sliding coefficient of friction. The aim was to determine the so called Stribeck-curve of any material in contact. The design of the plant is presented. Avoiding errors in recalculating the coefficient
