METHOD OF DETERMINING MECHANICAL STRESS IN RAILS Russian patent published in 2014 - IPC G01L1/12 

FIELD: physics.

SUBSTANCE: method of determining mechanical stress in rails involves mounting scanning devices 2-5 mm over the unprepared surface of each rail parallel to each other, said devices measuring remnant magnetisation of the metal of the rails. The scanning devices are connected to a receiving device mounted on a device moving on the rails. Remnant magnetisation data obtained during movement of the scanning devices are converted using software into data of mechanical stress in the rails. The obtained results are recorded in real time and stored in a storage unit.

EFFECT: high accuracy and continuous measurement of mechanical stress, easier measurement.
