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。
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.
结果表明，油膜涡动角度的变化对三油楔固定瓦滑动轴承的静、动特性和稳定性将产生很大的影响，且这种影响随油膜涡动半径增大而增大。
The results show that the change of oil-film whirl angle makes the characteristics of journal bearing change greatly, and the more the whirl radius is, the more the influence is.
因此，这种现象称为“油膜振荡”或“共振涡动。”
This phenomenon is therefore known as "oil whip" or "resonant whirl".
