滚动轴承的包络诊断方法

The Envelope Method in Rolling Bearing Faults Diagnosis

本文根据移频细化和希尔伯特变换求包络原理,提出一种细化包络分析方法,改进了常规软件包络技术.最后给出了该方法在滚动轴承故障诊断中的应用.

This paper presents a zoom envelope analysis method, based on the principle of frequency zoom and Hilbert transform. The method improves the general software envelope technipue. Finafly, this paper gives the application of the method in rolling bearing faults diagnosis.
