RESUMO

Several times the mechanical systems join the behavior described by laws of motion to the dynamic of their operation. Their solution pass by adopted simplified hypotheses in order to obtain a representative and helpful mathematical model. When the energy source used in the bringing to the action of the motion has limited power, i.e., there is not sufficient power in the motor for a proper working of the mechanism and the dynamic system is called nonideal. On this supposition, we numerically investigate in this work the nonlinear system of a specific problem looking for identify the nonideal and nonlinear conditions of the motion. Classical techniques of analyses of nonlinear systems are used, however it is develop a new numerical approaching, able to describe the dynamical behavior of the main solutions of the system. This technique consists in the calculation of the polynomials functions that describe the stability of a set of solutions concerning a bounded region on the phase portrait and they also provide a complete bifurcation diagram of the solutions without that any simplification in the diferential equations has been done
