主要基于转子—轴承系统阐述流体诱发失稳现象产生的机理和发生的条件，描述涡动和振荡的现象，并结合实例描述识别流体诱发失稳的信号特征，针对其产生的机理和发生的条件提出相应解决措施。%This paper clarifies the mechanisms and conditions influid-induced instabilities of rotor based on shaft-bearing system in turbogenerator sets, describes whirl and whip, gives some examples to describe and identify signal characteristics of fluid-induced instabilities. In the end, some solving projects are presented to eliminate these unstable vibrations.
