Duffing振子混沌运动的数值仿真分析

Numerical Simulation Analysis of Chaotic Moving of Duffing Oscillator

本文用Runge-Kutta法对Holmes型Duffing振子的混沌运动进行了分析,定义了描述该运动的几个概念,得出了Duffing振子由混沌运动到周期运动过渡时对外界微弱作用具有敏感性,指出了Duffing振子不同的运动状态是由不同的参数决定的结论。

This paper analyses chaotic moving of Holmes’ Duffing Oscillator by Runge-Kutta method, gives several conceptions to describe its moving, gains Duffing Oscillator sensitive to outside weak action when it moves from chaotic situation to periodic situation, and points out that different situations of Duffing Oscillator are decided by different parameters.
