摘要
从单摆问题引出Duffing方程问题,推出了关于Duffing振子的单摆运动方程.利用Matlab进行数值仿真模拟,分析了其运动中的分岔、Lyapunov指数和混沌等非线性特征.
The problem of Duffing equation single pendulum motion equation of Duffing movement with the nonlinear features such is deduced from the pendulum problem, from which it can deduce the oscillator. The computer is used to help the numerical simulation of its as bifurcation, chaos, Lyapunov exponent and so on.
