(Main)Railway applications - Crashworthiness requirements for rail vehicles
Railway applications - Crashworthiness requirements for rail vehicles
This document specifies crashworthiness requirements applicable to new designs of:
- locomotives;
- driving vehicles operating in passenger and freight trains;
- passenger rail vehicles operating in passenger trains (such as trams, metros, mainline trains).
This document identifies common methods of providing passive safety that can be adapted to suit individual vehicle requirements.
This document specifies the characteristics of reference obstacle models for use with the design collision scenarios.
This document also specifies the requirements and methods for demonstrating that the passive safety objectives have been achieved by comparison with existing proven designs, numerical simulation, component or full-size tests, or a combination of all these methods.
Bahnanwendungen - Anforderungen an die Kollisionssicherheit von Schienenfahrzeugen
Dieses Dokument legt Anforderungen fest an die Kollisionssicherheit für Neukonstruktionen von:
Lokomotiven,
Wagen mit Steuerkopf, die in Personen- und Güterzügen eingesetzt werden,
Personenschienenfahrzeugen in Personenzügen (wie Straßenbahnen, U Bahnen, Vollbahnzügen).
Dieses Dokument spezifiziert allgemeine Methoden zur Bereitstellung passiver Sicherheit, die angepasst werden können, um individuellen Fahrzeuganforderungen zu entsprechen.
Dieses Dokument legt die Eigenschaften von Referenzhindernismodellen, die in den Auslegungs-Kollisionsszenarien angewendet werden fest.
Dieses Dokument spezifiziert auch die Anforderungen und Verfahren, wenn der Nachweis der Erfüllung der passiven Sicherheitsziele über einen Vergleich mit bestehenden erprobten Konstruktionen, über numerische Simulation, über Versuche mit Bauteilen, über Prüfung in Originalgröße oder über eine Kombination all dieser Methoden erfolgt.
Applications ferroviaires - Exigences d'aptitude à la collision relatives aux caisses des véhicules ferroviairesferroviaires
Le présent document spécifie les exigences de l’aptitude à la collision applicables aux nouvelles conceptions de :
- locomotives ;
- véhicules avec cabine de conduite en exploitation dans des trains de passagers et de marchandises ;
- véhicules ferroviaires destinés au transport de passagers en exploitation dans des trains de passagers (tels que tramways, métros, trains de grande ligne).
Le présent document identifie les méthodes courantes de sécurité passive qui peuvent être adaptées pour convenir aux exigences particulières de chaque véhicule.
Le présent document spécifie les caractéristiques des modèles d'obstacles de référence pour les scénarios de collision de conception.
Le présent document spécifie également les exigences et les méthodes permettant de démontrer que les objectifs de sécurité passive sont atteints par comparaison avec les conceptions éprouvées actuelles, par simulation numérique, par des essais de composants ou des essais en grandeur réelle, ou une combinaison de toutes ces méthodes.
