We consider a simple friction oscillator with one degree of freedom using a non‐smooth, three‐parameter fricion model accounting for both, a decreasing and increasing dynamic friction force depending on the relative velocity. An analysis of global non‐smooth bifurcations is performed numerically and parameter domains are computed for the existence of stick‐slip oscillations. Special emphasis is placed upon the occurrence of stick‐slip oscillations with negative relative velocity. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
