Titre : Approximate analytical model for hertzian elliptical wheel/rail or wheel/crossing contact problems Type de document : texte imprimé Auteurs : F.D. Fischer, Auteur ; M. Wiest, Auteur Année de publication : 2015 Article en page(s) : 3 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Pressure  Approximation  Elastic  constants  Rails  Wheels Résumé : The Hertzian contact theory is approximated according to a concept by Tanaka (2001, “A New Calculation Method of Hertz Elliptical Contact Pressure ,” ASME J. Tribol., 123, pp. 887–889) yielding simple analytical expressions for the elliptical semi-axes, the maximum contact pressure, the mutual approach and the contact spring constant. Several configurations are compared using the exact Hertz theory and the current approximation. The results agree within technical accuracy.
