In this article, authors describe the development of a method of controlling the stress-strain and structural state of locomotive wheels during fabrication and service by taking use of plasma hardening technique on the basis of computer modeling of the deformation process and structural transformations taking place in this process.

The on-line fault detection of locomotive wheel plays an important role in improving the safety of locomo-tive.
