    基于虛擬儀器技術的滾動軸承故障診斷的包絡分析

    2007-11-14

    摘  要:分析了滾動軸承典型故障產生機理及其故障特征頻率,利用Hilbert變換的包絡分析法分析滾動軸承故障特征的思想,并且結合現代虛擬儀器技術設計并開發出實用的齒輪箱滾動軸承故障診斷系統。該診斷系統是我們自主開發的VMIDS系統基礎上開發出的智能控件化虛擬式滾動軸承故障診斷系統,在成功完成故障信息提取的同時,能降低系統的成本。   關鍵詞:虛擬儀器;故障診斷;包絡;滾動軸承   中圖分類號:TP311.52  文獻標識碼:A 文章編號:1672-4984(2007)04-0009-04   Envelope analysis for rolling bearings faults based on virtual instrument technology PAN Fei1, QIN Shu-ren2, BO Lin2 (1.Chongqing Communication Research and Design Institute,Chongqing 400067,China; 2.Test Center,Chongqing University,Chongqing 400044,China)   Abstract: This paper analyzed the principle and characteristic frequency of typical faults of rolling bearings and proposed a diagnosis system for rolling bearings faults which combine modern virtual instrument technology and thought of analyzing rolling bearings faults through Hilbert transform envelop analysis method. This system  based on VMIDS, which was developed by Test Center of Chongqing University and can successfully extract faults information as well as cut off the cost of system.
