摘要

A two-degree-of-freedom vibro-impact system is considered in this paper. The dynamical model and Poincare map are established. When pairs of complex conjugate eigenvalues of the Jacobi matrix cross the unit circle and satisfy the conditions of resonance cases, some dynamical behaviors of vibro-impact system are investigated by theoretical analysis. Furthermore torus oscillation, phase locking and evolutive route to chaos via torus bifurcations are discussed by numerical simulations.
