Dynamic Behaviors of a Two-Degree-of-Freedom Impact Oscillator with Two-Sided Constraints

Figure 4

The result of the numerical continuation of the period-2 solution with respect to the frequency . The solid and dashed orbits denote stable and unstable solutions, respectively. Bifurcation points are marked by black dots. (a) Two orbits of period-2 originated from the period-doubling bifurcation points PD1 and PD3 of the period-1 orbit, respectively. (b) Two orbits of period-2 originated from the period-doubling bifurcation points PD5 and PD7 of the period-1 orbit, respectively.
