Bifurcations of Oscillatory and Rotational Solutions of Double Pendulum with Parametric Vertical Excitation
Figure 3
Bifurcation diagrams of oscillations of the double pendulum (Figure 1) in two-parameter space using 2 methods. (a) Curves from Figure 2(a) (1 : 1 : 1 resonance). (b) Detailed view in Figure 3(b). (c) Curves from Figure 2(c) (2 : 1 : 1 resonance). Initial conditions for numerical integration (, , , and ). Abbreviations of bifurcations: SN: saddle-node, PD: period doubling, and SB: symmetry breaking.
