In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy source of limited power supply (non ideal problem). The mechanical system consists of an oscillating system sliding on a moving belt driven by a limited power supply. In the oscillating system considered here, dry friction acts as an excitation mechanism for stick-slip oscillations. The stick-slip chaotic oscillations are investigated because the knowledge of their dynamic characteristics is an important step in system design and control. Many engineering systems present stick-slip chaotic oscillations such as machine tools, oil well drillstrings, car brakes and others.2663-2668engDC motorsElastic moduliFrictionMachine toolsNonlinear systemsOscillationsSystems analysisSelf-excited systemsStick-slip chaosChaos theoryTrabalho apresentado em evento10.1115/DETC2003/VIB-48628Acesso aberto2-s2.0-1842631952
