基于虚拟仪器的滚动轴承振动故障诊断系统

Study on Fault Diagnosis System for Roller Bearing Based on Virtual Instrument

介绍了小波变换在滚动轴承故障特征提取中的应用.结合小波变换研制了一套滚动轴承故障诊断虚拟仪器系统.通过对滚动轴承振动信号的小波变换分析,可提取滚动轴承运行状态的特征向量,分析滚动轴承的振动信号,诊断轴承的故障.

The application of wavelet transform to roller bearings fault feature extraction is introduced in this paper. A kind of fault diagnosis system for roller bearing based on Virtual Instrument is studied. An effective diagnosis was made for the faults of the rolling bearings by using the wavelet analysis.
