The mathematical modelling of dry friction forces result in strong nonlinear equations of motion. The bifurcation behaviour of a deterministic system has been investigated by the bifurcation theory. The stability of stationary solutions has been analyzed by the eigenvalues of the Jacobian. Period doublings and Hopf-bifurcations as well as turning points could be determined with the program package BIFPACK. Phase plane plots of periodic and chaotic motions have been shown for a better understanding of the bifurcation diagrams. Both, unstable branches and stable coexisting solutions have been calculated. Several jumping effects, which are typical for nonlinear systems, have been found."}],"publication":"Bifurcation and Chaos: Analysis, Algorithms, Applications","doi":"10.1007/978-3-0348-7004-7_44","date_updated":"2022-01-06T07:04:05Z","volume":97,"author":[{"first_name":"Peter","full_name":"Stelter, Peter","last_name":"Stelter"},{"full_name":"Sextro, Walter","id":"21220","last_name":"Sextro","first_name":"Walter"}],"intvolume":"        97","page":"343-347","citation":{"ama":"Stelter P, Sextro W.
