BEHAVIOUR OF THE METAL OF THE RAILS AND WHEELS IN THE CONTACT ZONE--ENQUIRY INTO THE PROBLEM OF SMALL DIAMETER WHEELS APPENDIX 3

The observations made at the Mairy mine concerning the wheel-rail dynamics are discussed. The width of the rolling band is wider than on the SNCF and can be explained by wear of the wheel and rail. It could also be due to transverse elastic deformation of the wheel. The calculations and measurements are summarized which were carried out in the laboratory of the SNCF to investigate the influence of the load, the curvature of the rail and the tire, and more particularly of wheel diameter on the stresses to which these components are subjected.
