Abstract Scope |
The axle bearing of a railway vehicle is one of the parts that play an important role in driving the axle. In case of bearing damage or abnormality, a major accident may occur while the railway vehicle is running. Therefore, it is important to manage the abnormal condition of the axle bearings. Bearing abnormalities are usually managed by monitoring the bearing temperature. European EN standards monitor the temperature by installing a temperature monitoring device around the wayside, and recommends that a bearing temperature monitoring device for high-speed railways over 250km/h. In this study, infrared thermography technology was applied to monitor the axle bearing temperature. A temperature monitoring system was developed by installing a small infrared camera on the upper part of the axle and measuring the temperature outside the axle box on the vehicle. In this presentation, infrared thermal imaging sensing, operation program, and experimental results will be introduced. |
