| Abstract: | A mechanical model of a three-degree-of-freedom vibro-impact system is considered in this paper by using the analytical method to solve. Via analyzing the boundary condition under periodic motion of the system, the analytical solution of the periodic motion system is deduced ; Making use of the boundary conditions of disturbance movement to deduce the Poincaré mapping of the system, through numerical simulation and programming, the bifurcation and chaos of nonlinear movement oc- curring in system is analyzed. |
