Design of Railway Journal Box Embedded with FBG Sensor to Monitor Temperature and Acoustic Emission Signal

Abstract:

Railway journal box is designed to monitor the temperature and acoustic emission signal from the axle continuously. Fiber Bragg gratings (FBG) sensors are embedded inside of the journal box cover. Three types of journal box cover are designed such as front elbow coupler type, side hose type and side coupler type. Sensors and optical fiber are located on the predetermined positions engraved inside of the cover. Optical fiber egresses out of the surface and is protected in the protection tube. Among the three types of journal box cover, the side coupler model could be used most effectively.
