Abstract.
The nonlinear forced
vibrations of magnetization and elastic displacement in normal magnetized
ferrite plate having magnetoelastic properties are investigated. For modeling
of these vibrations the simplified system of two connected oscillators, one of which
has magnetoelastic properties, is proposed. On the basis of this model the possibility
of excitation of forced vibrations having auto-modulation character is shown. It
is found six frame auto-modulation vibration regimes. For their interpretation
two models are proposed: generalized potential and harmonic frequency
generation.
