Abstract
Keywords: mechanical vibro impact system, bifurcation diagram, largest Ljapunow exponents, attractors, Poincare sections.
In this paper, a mechanical vibro impact system with two degrees of freedom is analyzed. The dynamical behavior of the system is determined using different tools from dynamical systems theory, including bifurcation diagrams, largest Lyapunov exponent, and Poincare cross sections. Depending on the angular velocity of the excitation, the system shows both periodic and chaotic behavior. The same procedure is than used to examine the possibility of chaotic behavior of quarter vehicle model.
