Abstract:

Based on fiber Bragg grating sensing technology, we designed an online monitoring system for the pantograph of an electric locomotive. It could monitor realtime dynamic pressure, vibration state, slide stress and temperature of the pantograph. Through simulation, calibration and
testing, we acquired monitoring range of dynamic pressure of 0 ~500 N, and monitoring scope of microstrain of -0.2% ~0.2%.
