State Inspection and Fault Diagnosis System of Train Axel Box Bearing Based on Virtual Instrument
Key Engineering Materials(2016)
Abstract
Fault diagnosis of train bearing is an important method to ensure the security of railway. In the paper, four time domain statistical analysis methods and resonance demodulation method as a frequency domain analysis method are introduced. A state inspection and fault diagnosis system of train axel box bearing is constructed and its efficiency is also tested by wheel set experiment.
