摘要
应用以快速傅里叶变换(FFT)为基础的数字式实时频谱分析系统(SSPFX)对故障状态下汽轮机大轴的振动信号进行分析,得出了故障性质为油膜失稳的结论。
The analysis of the vibrorecord of a steam turbine rotor in the state of accident is conducted by using a digital real-time spectrum analysis system (SSPFX) based on FFT. The conclusion that the nature of the accident makes the oil film whip is obtained in the paper.
