A theoretical and experimental investigation of quasi-harmonic friction-induced vibration is reported. The vibration is of near-sinusoidal form and is solely governed by dynamic friction forces. However, the friction-velocity curve must be of a particular shape for the vibration to occur. The amplitude of the quasi-harmonic vibration is shown to increase with sliding velocity until oscillation ceases at some upper velocity boundary. The introduction of suitable damping will quench the vibration entirely. The vibration can exist at high sliding velocities and as a consequence may influence the operation of automatic transmissions, brakes, and clutches.read more

Slip motion and stability of a single degree of freedom elastic system with rate and state dependent friction
TL;DR: In this article, the authors consider a single degree of freedom elastic system undergoing frictional slip, where the system is represented by a block (slider) slipping at speed V and connected by a spring of stiffness k to a point at which motion is enforced at speedV 0.

Friction modeling for dynamic system simulation
TL;DR: It is clear that multi-scale effects can dominate performance of friction contacts, and as a result more research is needed into computational tools and approaches capable of resolving the diverse length scales present in many practical problems.
