挤压油膜阻尼器—滑动轴承—柔性转子系统是一类强的非线性动力系统，其中包含一些复杂的非线性现象，文中主要对系统的非谐调运动、突跳行为进行了理论分析。研究表明：系统存在二次Ｈｏｐｆ分岔，并导致准周期运动；存在重复的倍周期分岔，导致次谐运动；突跳是鞍—结分岔产生的结果。
Squeeze film damper - sliding bearing - flexible rotor system is a kind of strong non-linear dynamic system, which contains some complex nonlinear phenomena. The paper mainly analyzes the non-harmonic motion and sudden jump behavior of the system. The results show that the system has quadratic Hopf bifurcation and leads to quasi-periodic motions. There exist repeated period bifurcations, resulting in subharmonic motions. Kickstops are the result of saddle-junction bifurcation.
