The paper presents numerical simulation and graphical analysis of a mechanical vibro-impact system actuated by a harmonic force. The analytical study shows chaotic behavior of the mechanical system with two degrees of freedom and also the influence of initial conditions. Numerical results obtained using Runge-Kutta numerical method for solving differential equations were programmed in C, for different values of mechanical system parameters and initial conditions.

Key words:  vibro-impact systems, nonlinear differential equations, Runge-Kutta method, chaos.
