Abstract:

The Federal Railroad Administration (FRA) sponsored a research team from Oklahoma State University (OSU) to assess how well Optical Fiber Sensors (OFS), specifically Fiber Bragg Grating (FBG) sensors, can monitor railroad track transitions. The initial laboratory work focused on comparing the strains and deflections in a section of statically-loaded rail. The team collected strain gage and linear transducer data for comparison to FBG sensors and numerical modelling predictions. The results show good agreement between the methods, providing confidence in this new measurement technique. Additional planned research includes dynamic load tests and experiments to determine the best way to mount the FBG-sensor to the rail.
