چکیده
This paper discusses the application of fiber-optic technologies in measuring parameters stress-strain state a seamless track rail. Measuring modules are attached directly to side surface rail and contain sensors with special structure for changing refractive index along length base part. The values deformations determined during full-scale measurements when analyzing changes light pulses passing through an optical channel Bragg gratings. implemented approaches simulation relevant sections railway that most susceptible large gradient values, example, at turnouts, places subgrade heaving, etc.

Fiber-Optic Sensing Technologies
The fiber optics and optoelectronics industry has experienced a tremendous amount of innovation over the past four decades. Initially conceived for medical endoscopic applications, optical fibers were considered in the mid-1960s as an adequate technology for telecommunications applications. Since then, light wave communications systems have become the preferred and standard method to transmit v...
متن کاملMonitoring of Railway Deformations using Distributed Fiber Optic Sensors
Natural phenomena like earthquakes, landslides, avalanches or mud flows can cause severe damages of railway tracks. Today’s monitoring concepts either focus on a permanent monitoring of known problematic sites or an epochwise measurement of the railway track with special measurement cars. In this paper we present a new approach for continuous monitoring of railway tracks over long distances. Th...

متن کاملFiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)
The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...
