The considered model is taken as a Duffing system that is excited by two unbalanced direct current motors with limited power supplies. The results obtained by using numerical simulations are discussed in details.391-395engNon-ideal systemNonlinear systemSelf-synchronizationComputer simulationDC motorsElectric excitationElectric power supplies to apparatusKinematicsMathematical modelsNumerical analysisSynchronizationTorqueVibrations (mechanical)Duffing systemNon-ideal systemsNonlinear systemsArtigo10.1590/S1678-58782003000400011S1678-58782003000400011Acesso aberto2-s2.0-03481445752-s2.0-0348144575.pdf
