Monitoring of Rail Wheel Impact for Various Train Speeds

In today's era, monitoring train speed is an important factor in structural health monitoring of trains in railways. In this work, finite element analysis has been done for rail wheel model using ANSYS15.0 software. Simulation of Fiber Bragg Grating sensor is done by GratingMOD. Here train speed varies from 20 to 80kmph to observe the stress and strain response on the rail, with maximum stress, 190.96 MPa, strain of 111.89e-5mm and total deformation of 697.4mm, at constant wagon weight 57.3tons. Shift in Bragg's wavelength is 1551.4845nm at maximum speed, 80 kmph.
