| Abstract: | Based on the cell mapping method and in view of the characteristics of non - smooth dynamical systems with impacts, a new cell mapping method is introduced to investigate the global character of vibro - impact systems. As an illustrative example, Duffing oscillator with one - side constraint is investigated. The numerical results show that coexistent attractors, domains of attraction and complicated boundary embedded with the unstable invariant set well demonstrate the validity of the presented method. |
