Abstract

This paper proposes the use of FBG sensor to measure the lateral and vertical forces at the rail-wheel contact point. The ratio of lateral and vertical force at the flange contact contact point is called Nadal limit for a certain critical value for which derailment is likely to occur. Simulation has been done for the measurement of lateral and vertical forces with the increasing velocity and taking the range of radius of curve from 600m to 1000m.
