Question

One of the major problems that railway industries have faced since the earliest days is the prevention of service failures in running rail. As is the case will all modes of high-speed travel, failures of an essential component can have serious consequences. Rail is manufactured in different weights and conditions, and therefore, there are pursued a significant number of potential defects. In order to overcome the failure to occur during operating, a special predictive tool needs to be implemented to make sure the rail is safe and operating in normal condition. Thus, the objective of this project is to enhance the predictive monitoring assessment system for the railway running rail by estimating the fracture damage behaviour of the rail structure. The fibre optics will be used as a sensor device to measure the signal of the strain-stress in running rail. Suggest the steps or procedures that need to be carried out to measure the strain-stress signal in the railway running rail. Is that any possible errors that might be existing while capturing the data?

Answer 1

An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.

Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.

Solution of the given problems:

conditon given:

Railway industries have faced several problems from the earliest days is failure of rail during the service condition.

We have design the project in such a manner that stress strain analysis can be found in the service condition during the railway in service condition.

solution:

1) As the optical signal is used to trasmit the electrical signal from one point to another accurately.

2) Different mechanical gauges should be connected with the optical srnsor as that could be used to transmit the information of stress strain analysis at different cindition of rail during the running condition of the rail.

3) As the optical fibre is much accurate in trasmitting electrical signals than wires there is very less chance of fedding the signal or if it will fade with very small error .

4) As the mechanical gauge is used to do the strain stress analysis of the different mechanical component find the yieding of the several component and if the yield point is found more than the specified level than it will transmit the electrical signal with the help of optical fibre,

5)As this could be used to give warning to the rail operater and save the lives of person from any failure of railway in running condition.
