摘要
介绍了转子系统油膜涡动及油膜振荡的产生机理和故障特征。对转子实验台升速过程的振动信号进行了分析,揭示了转子系统油膜涡动和油膜振荡的发生过程。对典型油膜涡动和油膜振荡信号进行了时频分析,揭示出油膜涡动和油膜振荡的故障特征。
Generation mechanism and fault feature of oil whirl and oil whip for rotor system are introduced in this paper. Vibration signal got from lifting speed process of rotor text bed is analyzed, and generation process of oil whirl and oil whip is revealed. Typical oil whirl signal and typical oil whip signal are analyzed with time-frequency analysis, and fault features of oil whirl and whip are also revealed.
