Within the city limits, trains are restricted to a maximum speed of 70 kilometres per hour. However, the velocity of railways operating within the city is not constant. The railway will either speed up or slow down in order to travel a short distance and arrive at the station in a short amount of time. Depending on the speeds of the various movements, the structure of the rail will be impacted in various ways. This can be found by analysing the pattern behaviour of the graph depicting the FBG sensor's wavelength-shifting output. In this study, the FBG sensor is attached to the web surface of the rail at three distinct sites, each of which is subjected to a different speed. In this specific experiment, just the vertical orientation of the FBG sensor was taken into account. The railway travels at an accelerated rate of 40 kilometres per hour, a decelerated rate of 49 kilometres per hour, and a constant top speed rate of 67 kilometres per hour. When seen from three different locations, the graph of wavelength shifting displays three distinct patterns of behaviour. Based on the graph of wavelength shifting, the maximum speed is where the rail is under the most stress. The higher the railway's speed, the larger the force exerted to the rail and the magnitude of the strain placed on the rail. [ABSTRACT FROM AUTHOR] |
