摘要(Abstract)：
亚异步不稳定振动是由于转子上作用一个与位移相垂直的切向力,该力推动转子在涡动轨道上作功,本文从切向力作功量大小来分析转子的稳定性,描述了可能存在于透平压缩机械上的几种切向力及其各种故障特征。
The subsynchronous vibration is a transverse force which is perpendicular to the rotor displacement, and pushes the rotor whirling and working in orbit. In this paper, the stability of rotor is analysed by working level, some transverse forces possibly presenting in turbines and compressors and various fault symtoms are discussed.
