Abstract: The rotor-bearing system was modeled with consideration of different types of lubrication bearings. The stability of the rotor systems are then investigated. The logarithmic attenuation of the rotor-bearing system with different bearing parameters was studied. Via comparison, the influence of some key parameters on the shaft stability was discussed.

Key words: vibration and wave , rotor-bearing , lubrication bearings , shaft stability

摘要: 对滑动轴承型式试验台转子—轴承系统进行建模仿真计算,改变所采用的滑动轴承型式,研究主要常用滑动轴承对转子―轴承系统稳定性的影响。针对同一种轴承形式,研究不同轴承参数下转子—轴承系统的对数衰减率,以此为判据分析轴系稳定性,通过对比分析,给出主要轴承参数对轴系稳定性的随主要轴承参数的变化规律。
