Abstract

PALACIOS, J. L.; BALTHAZAR, J. M.  and  BRASIL, R. M. L. R. F.. A short note on a nonlinear system vibrations under two non-ideal excitations. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2003, vol.25, n.4, pp. 391-395. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782003000400011.

This paper describes a nonlinear phenomenon in the dynamical behavior of a nonlinear system under two non-ideal excitations: the self-synchronization of unbalanced direct current motors. 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

Keywords : Nonlinear system; non-ideal system; self-synchronization.
