Oscilador eletromagnético caótico

Abstract

A mechanical oscillation can to generate chaotic movements through irregular vibrations. The study of chaotic mechanical oscillation is the objective of this work and for this we proposed a mechanical electro - magneto system that describes a physical model that treats the movement of a thread in a magnetic field. With numeric simulations, we studied the system using the fast Fourier transform, Lyapunov exponents, bifurcation diagram, Poincaré section, phase plane trajectories and graphs of the thread positions in time function that oscillate in periodic and chaotic movements.

Uma oscilação mecânica pode gerar movimentos caóticos através de vibrações irregulares. O estudo da oscilação mecânica caótica é o objetivo deste trabalho e para isto propomos um sistema eletro - magneto mecânico que descreve um modelo físico que trata do movimento de um fio em um campo magnético. Com simulações numéricas estudamos o sistema, usando a transformada rápida de Fourier, expoentes de Lyapunov, diagrama de bifurcação, seção de Poincaré, trajetórias de plano de fase e gráficos das posições do fio em função do tempo que oscila em movimentos periódicos e caóticos.
