基于振动信号频谱分析的回转机械故障诊断方法

Mechanical Failure Diagnosing Method Basing on Vibration Signal

比较了回转机械振动信号频谱分析的各种算法的优缺点 ,并详细介绍了高效的FFT FT算法来解决普通FFT算法所无法解决的分辨率和计算数据量的矛盾 ,最后通过对一台二氧化碳压缩机的谱分析来说明了FFT FT算法的优越性。

A valid method of FFT is introduced to analyse mechanical failure,which solves the traditional contradiction of operation precision and operation time in use of FFT.At last ,the arithmetic shows its advantage by means of the frequence precision analysis of one compressor.
