oil film whirl

基本解释

The result shows that oil-film whirl of sliding bearing with the turbine generator is easily influenced by the boundary conditions.
针对某船用汽轮发电机组出现的振动异常情况，通过机组振动测试分析，确定机组振动异常由轴承油膜涡动引起。
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.
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。

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。
