Rotational motion induced by vibration has been observed in various places and has been the subject of research.
We have introduced a Mexican hat-type potential excitation system as a simple dynamical system that induces such motions,
and are conducting numerical simulations in the hope of finding universality and generality in the system.
In previous studies, it was found that as the amplitude of the excitation external force is increased as a control parameter,
the system bifurcate from unidirectional rotational motion to chaotic diffusion.
After chaotic diffusion, it was found that a limit cycle without unidirectional rotational motion and chaos with a positive second Liapunov exponent occurs. |
