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.
針對某船用汽輪發電機組出現的振動異常情況，通過機組振動測試分析，確定機組振動異常由軸承油膜渦動引起。
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.
結果表明，油膜渦動角度的變化對三油楔固定瓦滑動軸承的靜、動特性和穩定性將産生很大的影響，且這種影響隨油膜渦動半逕增大而增大。

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.
認爲突發性振動原因是運行中轉子的油膜渦動和匝間短路、線圈膨脹受阻等引起的熱不平衡。
