External stability of a resonance in a nonlinear system with slowly changing variables |

| Abstract |
The external stability of resonances in nonlinear systems
with several slowly changing variables is analyzed.
The external stability is determined by the behavior
of the trajectories of the system on nonresonant segments
of motion apart from a small resonance zone [1].
For the motion along the nonresonant segments,
the resonant terms appear in the second approximation
of the averaging method and, if the evolution does not occur
in the first approximation, manifest themselves in secondary
resonant effects. Conditions for the external stability
of a resonance are stated in nonlinear formulation.
The method is illustrated by the case investigation
of the external stability of a resonance during the motion of
an asymmetric rigid body about a fixed point. A phase portrait
constructed for nonresonant segments is presented to illustrate
the evolution of the slow variables in the cases of externally
stable and externally unstable resonances. |
