摘要
建立了SFD-滑动轴承-刚性转子系统和柔性转子系统2种耦合动力模型,采用Runge-Kutta法对上述2种系统的动力学问题进行求解,进而对系统的稳定性和分叉行为进行了研究。研究表明:刚性转子系统能够在一定范围内保持稳定的单周期运动,随后进入准周期;而柔性转子系统则从单周期运动进入准周期、倍周期等运动形态;在此基础上分析了2种系统的不平衡响应曲线。
This paper established two mechanics models： SFD-sliding bearing rigid rotor system and flexible rotor system, adopting runge-kutta method to solve dynamic question of the above systems, and then researched stability and bifurcation behavior of the systems. The study has shown： rigid rotor system can keep stable periodic motion in a certain scope, following quasi-periodicity bifurcation. Otherwise, the flexible rotor system came to motion state of quasi-periodicity bifurcation, doubling bifurcation, and so on, from periodic motion. On the basis, the paper analyzed unbalanced response curve of the system.
