Railway applications - Axle design method

This document presents the stage of knowledge resulting from the Euraxles project about the design of the axle, and further steps to be taken.
It is the support:
- to define the loads to be taken into account;
- to describe the stress calculation method using finite elements and the validation processes associated;
- to specify the maximum permissible stresses to be assumed in calculations and the safety factors to be used.
This technical report is applicable for:
- wheelset Axles defined in EN 13261 as "pure wheelset";
- other axle designs such as those encountered in particular rolling stocks e.g. with independent wheels, variable gauges, urban rail...
This document has not for aim to replace EN 13103-1 and CEN/TS 13103-2 but to present a complementary method to the existing ones.

Bahnanwendungen - Konstruktionsverfahren von Radsatzwellen

Applications ferroviaires - Méthode de conception des essieux-axes

Le présent document décrit l'état des connaissances acquises dans le cadre du projet EURAXLES en ce qui concerne la conception des essieux-axes, ainsi que les autres éléments à prendre en compte.
Il a pour objet de :
- définir les charges à prendre en compte ;
- décrire la méthode de calcul des contraintes selon la méthode des éléments finis, ainsi que les processus de validation associés ;
- spécifier les contraintes maximales admissibles à utiliser pour les calculs, ainsi que les coefficients de sécurité à appliquer.
Le présent Rapport technique est applicable aux :
- essieux montés définis dans l'EN 13261 ;
- autres conceptions d'essieux-axes rencontrées sur les matériels roulants particuliers, par exemple les essieux-axes équipés de roues indépendantes, à écartement variable ou empruntant le réseau ferroviaire urbain, etc.
Le présent document n'a pas pour objet de remplacer l'EN 13103 1 et la CEN/TS 13103-2, mais de décrire une méthode complémentaire aux méthodes actuelles.
