Bahnanwendungen - Fahrkomfort für Fahrgäste - Messung und Auswertung

Diese Europäische Norm legt Methoden zur Bewertung der Auswirkungen von Bewegungen des Wagenkastens auf den Fahrkomfort für die Fahrgäste und für die Fahrzeugbemessung fest.
Die hier betrachteten Auswirkungen sind:
-   Unannehmlichkeiten in Verbindung mit relativ kleinen Beschleunigungen und Rollgeschwindigkeiten.
Andere Einflüsse in Zusammenhang mit höheren Beschleunigungspegeln sind nicht in dieser Norm erfasst:
-   Gesundheitsrisiko: körperliche Behinderung und psychische Störung.
Der Anwendungsbereich ist auf den öffentlichen Eisenbahnverkehr beschränkt, die Norm umfasst Schienenfahrzeuge, die zur Beförderung von Fahrgästen ausgelegt sind, einschließlich Neben- und Vorortstrecken. Sie kann aber auch als Leitfaden für andere Eisenbahnfahrzeuge, z. B. Lokomotiven, U Bahnen und Straßenbahnen usw. verwendet werden.
Diese Norm bezieht sich auf Fahrgäste, die sich in einem gesundheitlich guten Allgemeinzustand befinden.
Sie gilt für Bewegungsmessungen, kann aber auch für Simulationen angewendet werden

Applications ferroviaires - Confort de marche des voyageurs - Mesurage et évaluation

La présente Norme européenne spécifie des méthodes de détermination des effets des mouvements de la caisse sur le confort de marche des voyageurs et d’évaluation du véhicule du point de vue du confort de marche. L’effet considéré est :
-   l’inconfort, lié à des niveaux d’accélération et une vitesse de roulis relativement faibles.
Les autres effets, non couverts par la présente norme, sont liés à des niveaux d’accélération plus élevés :
-   risques pour la santé : Dommages physiques et psychologiques.
L’objet de la présente norme se limite au service ferroviaire public ; la norme concerne les véhicules ferroviaires de transport de voyageurs sur des lignes ferroviaires, incluant les lignes secondaires et les lignes de banlieue. Le présent document peut toutefois être utilisé comme guide pour d’autres véhicules ferroviaires comme par exemple les locomotives, les métros, les tramways, etc.
La norme s’applique à des voyageurs en bonne santé.
La présente norme s’applique aux mesurages des mouvements, mais elle peut également être utilisée pour des simulations.

1 Scope
This European Standard specifies methods for quantifying the effects of car body motions on ride comfort for
passengers and vehicle assessment with respect to ride comfort. The effect considered is:
 discomfort, associated with relatively low levels of acceleration and roll velocity.
Other effects, not included in the standard, are associated with higher acceleration levels:
 health risk effect: physical damage and psychological deterioration.
The scope of the standard is limited to public railway services; the standard includes railway vehicles designed for
carrying passengers travelling on railway lines, including secondary and suburban lines. However, this standard can
be used as a guide for other railway vehicles, for example locomotives, metros, trams, etc.
The standard applies to passengers in good health.
This standard applies to measurements of motions, but can also be used for simulations.
