Railway applications - Wheel-rail contact geometry parameters - Definitions and methods for evaluation

Le présent document établit les définitions et les méthodes d'évaluation relatives aux paramètres géométriques du contact roue-rail, qui influencent le comportement dynamique des véhicules ferroviaires. Ce document fournit également des informations concernant la relation entre les angles de contact des deux roues d'un essieu (fonction ¿tan¿) et le paramètre d'angle de roulis. Les exigences minimales pour la mesure des profils de roue et de rail, ainsi que les paramètres nécessaires à la déduction d'un système de coordonnées commun pour les profils droit et gauche sont spécifiées. Le présent document ne définit pas de limites pour les paramètres géométriques du contact roue-rail, ni de tolérances pour les profils de rail et de roue afin d'obtenir des résultats acceptables.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
