    • Aspects Regarding the Vibrations of the Contacts of a compressed air Switch 

      Dragomirescu, Cristian; Craifăleanu, Andrei (Universitatea "Dunărea de Jos" din Galați, 2007)
      The paper studies the vibrations of the contacts of a compressed air switch, by considering two models. Time variation of the elongation is presented, as well as spectral representations determined by means of Fourier ...

    • Study of the internal Resonance of a two-Degree-of-Freedom Non-Linear Dynamic System 

      Dragomirescu, Cristian; Craifăleanu, Andrei (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper analyses a two- degree- of- freedom dynamic system, by taking into account its non- linearity. The case of the internal resonance is studied and, by local analysis, Hopf bifurcations are emphasized. Periodic ...
