摘要

针对传动系统振动信号可能存在的故障特征不明显造成的故障识别困难问题,提出了一种基于变分模态分解和奇异值分解的特征提取方法,并采用模糊C均值聚类进行状态识别与监测。首先将齿轮箱各状态数据进行变分模态分解,并将各模态奇异值作为特征值,通过模糊聚类进行状态识别,最后应用于齿轮箱状态监测。结果表明,对于人工无法识别的齿轮箱故障,该方法故障识别率在86%以上,基于该方法的状态监测可为齿轮故障预警及严重程度提供参考。

Abstract

As to the fault diagnosis difficulty caused by the fact that fault feature is possible not obvious in mechanical transmission system,a method based on variational mode decomposition and FCM is proposed for gearbox condition monitoring. Firstly,the state data of the gearbox is decomposed into different modes,and the singular value of each mode is used as the feature value,and the state is identified by fuzzy clustering. The results show that the fault identification rate is above 86% for the gearbox fault of artificial unable to identify,and the condition monitoring based on the method can provide reference for the gear fault warning and severity.
