介绍了 FFT-FS频谱细化方法。这种方法在不增加采样点数的前提下 ,对感兴趣的频带进行细化 ,能够得到比较准确的频率值。并以某厂 R1轧机主传动系统的减速机为例 ,说明该方法是准确确定故障频率并进行诊断的有效方法。
The FFT-FS spectrum refinement method is introduced. This method does not increase the number of samples under the premise of the interested bands to refine, you can get a more accurate frequency value. Taking the reducer of the main transmission system of a mill R1 as an example, this method is an effective method to accurately determine the fault frequency and diagnose it.
