Jeffcott转子油膜稳定的定性分析

STABILITY OF JEFFCOTT'S RIGID ROTOR WITH OIL FILM

  • 摘要: 基于Muszynska刚性转子模型,对转子漏动的稳定性进行了分析研究.采用首次近似方程判断了转子漏动方程零解与极限坏的稳定性,确定了转子运动的稳定性条件.在极坐标系下首次给出了用三个状态方程表示的转子轴承系统的简捷方程.

     

    Abstract: Based on the mathematical model of Jef fcott's rigid rotor with oil film and linearized differential equation method, the stability of zeroth solution of rotor motion equation and its stability of self excited vibration are investigated in this paper.The conditions of stable rotation are obtained. Reduced phase equations of three dimensions are firstlyproposed.
