They are normal (without any fault), unbalance, radial rub, oil whirl and a simultaneous state of unbalance and radial rub. The first condition is normal, and the last four conditions are fault conditions.
本文共模拟转子的5种运行状态,一种为正常状态,另四种为故障状态包括不平衡、碰摩、涡动以及不平衡+碰摩。

This paper describes, analyses and diagnoses the oil whirl and whip faults in the tilting pad bearings of the 9f type gas generator set of single shaft.
对9f单轴式燃机发生在可倾瓦轴承上的油膜涡动和油膜振荡进行了介绍、分析和诊断。
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。”
It is concluded that the causes of sudden vibration are oil film whirl and thermal unbalance of generator rotor resulting from interturn short-circuit and hindered winding expansion etc.
认为突发性振动原因是运行中转子的油膜涡动和匝间短路、线圈膨胀受阻等引起的热不平衡。
