Definitions

  • the invention relates to a rail for rail vehicles with a tread mechanically treated against corrugation.
  • corrugation On the tread of the rail has been a phenomenon that has been known for decades. Despite long, intensive efforts to clarify the phenomenon of corrugation, there is still no clear explanation. According to the most recent long-term study in various regions, the corrugation is independent of the selected rail steel, its strength and its structure, although the austenitic and bainitic structure has proven to be less sensitive to corrugation. The cause of the corrugation then appears to be the imperfect rolling of the wheels on the rails with torsion and slip, which triggers changes in the rail surface and the wheels and contact vibrations and / or in the change in normal forces with alternating slip, non-uniform wear and excitation the natural rail frequencies.
  • the invention has for its object to provide a rail for rail vehicles with high resistance to corrugation.
  • This alpine pasture value can be influenced for different steels by the choice of the nozzle diameter, the nozzle spacing, the jet pressure, the jet angle and in particular the abrasive used.
  • the strength blasting was carried out on approximately 1.5 m long rail sections.
  • the surface condition and the position of the maximum residual compressive stress change with the Almen value, which is dependent on the blasting conditions.
  • the increase in the alpine pasture value due to larger blasting bodies with constant blasting time leads to an increase in the residual compressive stress and the depth of the maximum residual compressive stress with increasing surface roughness.
  • an Almen value of 0.5 A was set for the strength blasting of the rails and rail connections.
