摘　　要：建立挤压油膜阻尼器悬臂转子系统的动力模型。利用Runge-Kutta法求解转子系统运动微分方程,对转子动力响应和系统分叉现象进行研究,得出系统运动形态的变化,获得SFD悬臂转子滑动系统不平衡响应曲线,对转子系统的稳定性及结构优化具有重要的意义。系统模型是悬臂转轴模型,而不是经典Jeffcott转子模型。Established a dynamic model of a cantilever rotor system with squeeze film damper. RungeKutta is used to solve differential equation of rotor system and research the phenomena of rotor dynamic response and system bifurcation. The research contributes to the result that the change of the form motion of system and obtains the unbalance response curve of SFD-cantilever sliding rotor system. This result has great significance for the stability and structure optimization of the rotor system. The system model is the cantilever shaft model, which is the great characteristic in the paper, rather than traditional Jeffcott rotor model.
