Design and Application of Running-in Fault Detection Station for Passenger Vehicle Wheel Pairs
This paper designed a bus wheelset running-in bearing fault detection system based on the sensing system to achieve the visualisation of diagnostic results,so as to reduce human intervention and realise the accurate identification of health status.The bearing fault diagnosis system integrates signal acquisition,data processing,feature extraction and state detection.With the help of acceleration sensors and acquisition cards to obtain real-time information on bearing vibration,the vibration information is processed by algorithms,and the results are compared with the preset threshold value of vibration information of trouble-free bearings to realise real-time identification of axlebox bearings'state of health,and the results of the identification are displayed in a visual way.Using the test bench to carry out vibration signal acquisition,signal processing and other experiments.The experimental results show that the information data collected by the test bench is reliable,which can provide a guarantee for the subsequent determination of the threshold value of normal samples with high sensitivity and the diagnostic model with high accuracy.
