Abstract

Abstract:

The definition and algorithm of fractional cepstrum are introduced. A new machine fault diagnosis method based on fractional cepstrum is proposed. The experimental result shows that fractional cepstrum is superior to the traditional cepstrum. It can suppress the interference and enhance the quality of the diagram spectrum.

Key words: fractional Fourier transform, fractional cepstrum, fault diagnosis

摘要：

论述了分数倒谱的定义和算法，提出了一种基于分数倒谱的机械故障诊断方法。并与倒谱分析方法进行对比分析。实验研究表明，分数倒谱优于传统的倒频谱分析方法，分数倒谱能有效抑制干扰，提高图谱质量。
