Friction–vibration interactions

Abstract:

Generally, friction could be treated as a dynamical variable in a dynamical system with a sliding interface. For convenience, the effect of friction on vibrations and the effect of vibrations on friction have been treated separately. The close-loop feedback effects of friction–vibration interactions have rarely been paid attention due to limited engineering applications. Both friction and vibration have been simplified and quantified by order-reduced models. There are many unique dynamic phenomena and underlying mechanisms associated with the vibrations of a system with friction, just to name a few: stick-slip, self-excited vibrations, modal coupling, sprag-slip, loss of contact, parametric resonance, ...
