| 摘 要： | 对具有质量偏心仅考虑径向碰摩力非线性的Jeffcott转子模型,研究了其通向混沌的路径.研究结果发现,发生碰摩故障的转子系统有一条通过拟周期分岔而到达混沌的路径,进一步的研究表明拟周期路径由具有不同频率的模式锁合和分离实现.结论有利于旋转机械故障的识别,同时也为转子系统振动状态的控制提供了一定的理论依据.图2,参6.

| Abstract: | Based on a Jeffcott rotor model with nonlinear radial rub force, the approach to chaos is studied when the forcing frequency and nondimensional unbalanced mass are treated as control variables. The result of research manifests the rotor can arrive at chaos by way of quasi periodic bifurcation, which is one of the four manners to turn up chaos. Further research shows that this quasi periodic bifurcation comes true owing to the model locking with different frequency. In addition, the possibility of parametric adaptive control of rub rotor system is discussed.2figs.,6tabs. |
