Bifurcation sequences in the interaction of resonances in a model deriving from nonlinear rotordynamics: the zipper.

Using numerical continuation we show a new bifurcation scenario involving resonant periodic orbits in a parametrised four-dimensional autonomous system deriving from nonlinear rotordynamics. the scenario consists of a carefully orchestrated sequence of transcritical bifurcations in which branches or periodic solutions are exchanged. Collectively, the bifurcations resemble the action of a zipper. An underlying governing mechanism clearly exists but still has to be uncovered. For a range of parameter values the sequence of bifurcations forms a global connection between a Sil'nikov bifurcation and (partial) mode-locking. The homoclinic bifurcation is introduced into the system by a Takens-Bogdanov bifurcation. The system also features an interaction between two chaotic Sil'nikov bifurcations
