This phenomenon is therefore known as "oil whip" or "resonant whirl".
因此,这种现象称为“油膜振荡”或“共振涡动。”
Some practical examples for bearing oil whip fault diagnosis and the stator coil's overheating fault diagnosis of turbogenerators are given.
文中给出了该方法在汽轮发电机轴承油膜振荡故障和静子线圈过热故障诊断中的应用实例。
The analysis results also indicate rub-impact faults induced by oil-film instability can produce some low-frequency components with small amplitude and oil whip can produce half frequency component;
油膜失稳引起的转定子碰摩故障,会产生一些低频成分,油膜振荡会产生半频成分;
