| 摘 要： | 本文完善和改进了求解非线性常微分方程组周期解及分叉特性分析的ＰＮＦ方法，用以有效地分析谐波、次谐波运动和倍周期分叉行为。然后，应用该方法对一个单盘挠性转子－轴承系统的动力行为进行了研究。结果显示运动呈现拟周期分叉、倍周期分叉和切分叉等复杂动力学现象，并与一些理论和实验结论作了比较。

| Abstract: | his paper has improved the PNF method , which is used to determine the periodic solutions andbifurcating properties of the nonlinear ordinary differential equations, to analyze effectively the har-monics , sub-harmonics and peried-doublins bifurcation of this system. Then, the iniproved method isapplied to study a flexible single-disk rotor-bearing-support system- The results show many complicat-ed dynamic behaviors, such as pesudo-periodic bifurcation, period-doubling bifurcation and tangentbifurcation, And some theoretical and experimental conclusions are compared with the above analyzingresults. |
