4阶龙格库塔法和10阶连分式欧拉法 NonlinearDynamicsofDuffing
采用4阶龙格库塔法和10阶连分式欧拉法，数值计算、分析了分数阶阻尼Duffing系统的
动力学特性．利用相图、Poincare截面映射图和分岔图等非线性动力学分析方法研究了阻尼的分数
阶微积分阶数对Duffing系统动力学性能的影响，采用分岔图法研究了外部激励的幅值和频率变
化时分数阶阻尼Duffing系统的动力学行为．分析表明，分数阶阻尼的阶数在0．1～2．0发生变化
时，系统依次进入周期运动、混沌运动、周期运动、混沌运动和周期运动，并且在混沌运动区间中存
在着周期运动窗口，由周期运动进入混沌运动的倍周期过程比较明显，结果证实了阻尼的分数阶微
分阶数对系统的动力学特性影响比较大，因此在系统动力学设计和分析中应该重视．(Abstract：Nonlinear dynamics of Duffing system with fractional order damping is investigated。
The equations of fractional order damped Duffing system are established．The four-order Runge-
Kutta method and ten-order CFE-Euler methods are performed tO solve the fractional order Duffing
