| Abstract Scope |
The axlebox temperature monitoring system in real time of railway vehicle bogie was developed. The bogie of a railway vehicle is a device responsible for driving the vehicle. For stable operation of wheels and axles, bearings are mounted on the axlebox. In order to detect the wear or abnormal conditions of the bearings, the temperature of the bearing area is measured at the wayside, and the condition diagnosis of the bearing is performed by monitoring the occurrence of abnormal heat generation. In this study, for temperature measurement of the bearings, a device was built to monitor temperature distribution in axlebox area in real time using a small infrared camera. In addition, a thermocouple was mounted on the same site to perform a comparative analysis of the results obtained from the thermal image. It was found that it was in good agreement with the temperature values obtained through the thermocouple. |
