Dynamics of a kinematically excited system with chosen friction models

Stick-slip vibrations in a mechanical system with dry friction and kinematical excitation with chosen friction models in a stick phase are studied in this work. Although there are numerous works in the scientific literature dedicated to stick-slip vibrations, a rigid body lying on a belt which moves at non-constant velocity is less investigated. A novel friction model is used and its advantages, in comparison to the often applied friction models, are illustrated. The behavior of the system is monitored via standard motion analysis in the system’s phase space.
