This paper explores dynamical behaviour of a parametrical excited two-degree-of-freedom pendulum. It has been shown that as excitation period increases, existing period orbit could bifurcates into more-complex invariant manifolds. Complex behaviour of the system is studied by the means of phase portraits, Poincare sections, and Lyapunov exponents and it has concluded that system could become chaotic for some range of involving parameters.
