Railway applications - Aerodynamics - Part 5: Requirements and test procedures for aerodynamics in tunnels
This document establishes requirements, test procedures, assessment methods and acceptance criteria for aerodynamics in tunnels and rolling stock in tunnels. Topics of aerodynamic pressures and loadings, aerodynamic resistance and micro-pressure waves are addressed.
Requirements for rolling stock with operating speeds equal to or above 200 km/h are provided for pressures generated in tunnel operation. Requirements for infrastructure with design speeds above 160 km/h or high blockage ratio or tunnels longer than 12 km are provided for pressures generated in tunnel operation. These requirements are not applicable to light rail and urban rail.
This document is applicable to all railway vehicles and infrastructure with track gauges from 1 435 mm to 1 668 mm inclusive.
Bahnanwendungen - Aerodynamik - Teil 5: Anforderungen und Prüfverfahren für Aerodynamik im Tunnel
Dieses Dokument legt Anforderungen, Prüfverfahren, Beurteilungsverfahren und Abnahmekriterien für die Aerodynamik in Tunneln und von Schienenfahrzeugen in Tunneln fest. Die Themen des aerodynamischen Drucks und der aerodynamischen Beanspruchung sowie des aerodynamischen Widerstands und der Mikrodruckfelder werden behandelt.
Anforderungen an Schienenfahrzeuge mit Betriebsgeschwindigkeiten von mindestens 200 km/h werden für im Tunnelbetrieb erzeuge Drücke angegeben. Anforderungen an die Infrastruktur bei Bemessungsgeschwindigkeiten von mehr als 160 km/h oder höhere Versperrungsmaße im Betrieb in Tunneln mit einer Länge von mehr als 12 km sind für die im Tunnelbetrieb erzeugten Drücke vorgesehen. Diese Anforderungen gelten nicht für Stadtbahnen und städtische Schienenbahnen.
Dieses Dokument gilt für alle Schienenfahrzeuge und Infrastruktur mit Spurweiten von 1 435 mm bis einschließlich 1 668 mm.
Applications ferroviaires - Aerodynamique - Partie 5 : Exigences et procédures d'essai pour l'aérodynamique en tunnel
Le présent document spécifie les exigences, les procédures d'essai, les méthodes d'évaluation et les critères d'acceptation relatifs à l'aérodynamique et au matériel roulant dans les tunnels. Il aborde les pressions et charges aérodynamiques, la résistance aérodynamique et les micro-ondes de pression.
Il spécifie les exigences applicables au matériel roulant circulant à une vitesse supérieure ou égale à 200 km/h en matière de pressions générées lors de la traversée d'un tunnel. Il donne les exigences applicables aux infrastructures dont la vitesse de conception est supérieure à 160 km/h ou ayant un fort rapport de blocage, ainsi qu'aux tunnels mesurant plus de 12 km de longueur en matière de pressions générées lors de la traversée d'un tunnel. Ces exigences ne s'appliquent pas aux systèmes ferroviaires légers ni aux systèmes ferroviaires urbains.
Le présent document s'applique à l'ensemble des véhicules ferroviaires et infrastructures dont l'écartement de voie est compris entre 1 435 mm et 1 668 mm, valeurs extrêmes incluses.
