By using examples of the heavy rotor, as well as gyrorotor which rotates
about two or more axes with sections in one point or more points, or without
section, the rotodynamics is presented. For that reason, the mass moments
vectors for the pole in the stationary shaft bearing and for the different
rotate shaft axis, as well as kinematic rotator vectors are introduced.
For the selected examples of the solutions rotate equations, the analysis of
the static and dynamic equilibrium positions, as well as the structural
stability of the phase portrait are phase portrait, vector rotators as a
functions of the generalized angle coordinate of the deviator part of the mass
moment vectors. The analogy between motions of heavy material point: 1) on
the circle in vertical plane, 2) on the circle in vertical plane which rotate
around vertical axis in the plane or out of the circle plane, and 3) on the
sphere and corresponding motions case of the heavy rotor, as
well as of the gyrorotor which rotates around two, or more axes with
sections in one point or more points.
By using papers written by Ph. Holmes, as well as Smale-Birkhoff homoclinic theorem,
and Hartman Grobman stable manifold theorem for fixed point about local stable and
unstable manifold on the diffeomorfism with a hyperbolic homoclinic saddle fixed point the
heavy forced rotor oscillatory motion in the neighborhood around hyperbolic points was
studied. This forced motion under the action of the periodic couple excitations is stohastic
like and chaotic like oscillatory process with sensitive dependence on the initial
conditions. The Poincare maps are presented, as well as a Smale horse shoe maps.
It is studied nonlinear dynamics in the field of the turbulent damping for
different gyrorotor system parameters. Equations of the phase trajectories
family are determined, as well as special homoclinic orbits.
