Abstract
A non-ideal or finite power source system is characterized by the fact that the energy source who excites the system suffer at the same time an influence of the excitation itself, changing its normal behavior, especially when occurs a passage through the resonance. This occurs due to the coupling between the mechanical system and the system of the energy source. When near the resonance region, the power supply of this type of system, which can be an electric motor, an engine or a turbine, loses energy feeding only the vibration of the system and not its shaft rotation. The behavior of the ideal type system is already well known in the literature, but various non-ideal systems still presents as challenges for their complete understanding. This work presents the numerical analysis of a non-ideal type system made by a beam and two unbalanced electric motors. The dynamic model was obtained with the use of the Lagrangean formalism and was simulated numerically in MATLAB. For the results, several jump phenomena diagrams were obtained for different configurations of the system, showing the influence of the motors in the mechanical structure.
