Railway applications - Methods for calculation of stopping and slowing distances and immobilisation braking - Part 6: Step by step calculations for train sets or single vehicles

This European Standard describes a general algorithm that may be used in all types of high speed
and conventional vehicle applications, including self-propelling thermal or electric trains, thermal or
electric traction units; passenger carriages, mobile railway infrastructure construction and
maintenance equipment and freight wagons. This standard does not specify the performance
requirements. It enables the calculation of the various aspects of the performance: stopping or
slowing distances, dissipated energy, force calculations and immobilization braking.
This standard enables the verification by calculation of the stopping, slowing and immobilization
performance requirements for high speed and conventional trains operating on high speed and
conventional infrastructure.
This standard presents:
a) example of distance and other dynamic calculations, see Annex C;
b) example of immobilisation calculations, see Annex D.

Bahnanwendungen - Verfahren zur Berechnung der Anhalte- und Verzögerungsbremswege und der Feststellbremsung - Teil 6: Schrittweise Berechnungen für Zugverbände oder Einzelfahrzeuge

In dieser Europäischen Norm wird ein grundlegender Algorithmus beschrieben, der verwendet werden kann für alle Betriebsarten der konventionellen und Hochgeschwindigkeitsfahrzeuge, einschließlich selbst fahrender Züge und Einheiten, die elektrisch oder durch Verbrennungskraft getrieben werden, Reisezugwagen, mobile Arbeits- und Wartungsfahrzeuge und Güterwagen. Die vorliegende Norm enthält keine Anforderungen an das Bremsvermögen. Es ermöglicht, die verschiedenen Kriterien des Bremsvermögens zu berechnen: Wege der Anhalte- oder Regulierbremsung, Energiedissipation, Kraftberechnungen und Stillstandsbremsung.
Die vorliegende Norm ermöglicht es, Anforderungen an Anhalte-, Verzögerungs- sowie Stillstandsbremsver-mögen für konventionelle und Hochgeschwindigkeitszüge, die auf konventionellen und Hochgeschwindigkeits¬strecken verkehren, mittels Berechnungen zu überprüfen.
Andere Berechnungsmethoden können genutzt werden, vorausgesetzt, dass die Genauigkeit in Überein-stimmung mit dieser Europäischen Norm erreicht wird.
Die vorliegende Norm enthält:
a)   ein Beispiel der Weg- und anderer dynamischer Berechnungen, siehe Anhang C;
Berechnungsbeispiele einer Stillstandbremsung, siehe Anhang D.

Applications ferroviaires - Méthodes de calcul des distances d'arrêt, de ralentissement et d'immobilisation - Partie 6: Calculs pas à pas pour des compositions de trains ou véhicules isolés

La présente Norme européenne décrit l’algorithme général à utiliser pour les applications à tout type de
véhicule grande vitesse et conventionnel, y compris les trains automoteurs à traction thermique ou électrique,
les unités à traction thermique ou électrique, les voitures à voyageurs, les équipements mobiles de
construction et de maintenance d’infrastructure ferroviaire, et les wagons. La présente norme ne spécifie pas
les exigences de performances Elle permet de calculer les différents aspects des performances : distances
d’arrêt ou de ralentissement, énergie dissipée, calcul des efforts et freinage d’immobilisation.
La présente Norme européenne permet de vérifier au moyen de calcul, les exigences de performances
d’arrêt, de ralentissement et d’immobilisation des trains grande vitesse et conventionnels, circulant aussi bien
sur des infrastructures type « grande vitesse » que de type « rail conventionnel ».
D’autres méthodes de calcul peuvent être utilisées à condition que le niveau de précision atteint soit conforme
à la présente Norme européenne.
La présente norme présente :
a) un exemple de distance et autres calculs dynamiques, voir Annexe C ;
b) un exemple de calculs d’immobilisation, voir Annexe D.
