  text: Dry friction is a main factor of self-sustained oscillations in dynamic systems.
    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.
