Friction Force for Self-Excited Systems

TL;DR

This paper introduces a model for low friction in self-excited systems, demonstrating reduced energy dissipation and stick-slip behavior when a self-excited oscillator interacts with a periodic potential.

Contribution

It presents a novel model linking self-excitation with friction reduction and stick-slip phenomena in sliding systems.

Findings

Self-excitation influences stick-slip behavior.

Energy dissipation during sliding is reduced.

Frictional properties are modulated by self-excitation.

Abstract

The paper presents a model for low friction made up of a self-excited oscillator sliding along a periodic potential. It is shown that if the self-excitation affects a body sliding tangentially to a surface, than stick-slip modification and reduction of energy dissipation during the motion are observed.
