Railway applications - Method for determining the equivalent conicity

This European Standard establishes an evaluation procedure for determining equivalent conicity. A benchmark calculation is specified to achieve comparable results on a consistent basis for the equivalent conicity, which may be calculated by different methods not given in this European Standard. This European Standard also proposes possible calculation methods. Informative examples of the use of the Klingel formula (see Annex B) and linear regression of the Δr-function (see Annex C) are included in this European Standard. This European Standard includes reference profiles, profile combinations, tolerances and reference results with tolerance limits, which allow the user to assess the acceptability of a measuring and calculation system including random- and grid- errors of the measuring system. It sets down the principles of calculation that need to be followed but does not impose any particular numerical calculation method. This European Standard does not define limits for the equivalent conicity and gives no tolerances for the rail profile and the wheel profile to achieve acceptable results for the conicity. For purposes outside the scope of this European Standard (e.g. simulation of vehicle behaviour) it can be useful or necessary to use more sophisticated theories. These methods are not within the scope of this European Standard. For the application of this European Standard some general recommendations are given in Annex I.

Bahnanwendungen - Verfahren zur Bestimmung der äquivalenten Konizität

Diese Europäische Norm legt ein Bewertungsverfahren zur Bestimmung der äquivalenten Konizität fest. Es wird eine Vergleichsberechnung spezifiziert, mit Hilfe derer vergleichbare Ergebnisse für die äquivalente Konizität auf einer einheitlichen Basis erzielt werden können. Diese Ergebnisse können mit anderen als in dieser Europäischen Norm angegebenen Verfahren berechnet werden. In diesem Dokument werden auch mögliche Berechnungsverfahren vorgeschlagen. Es enthält außerdem informative Beispiele zur Anwendung der Klingelschen Formel (siehe Anhang B) und der linearen Regression der Funktion Δr (siehe Anhang C).
Diese Europäische Norm beinhaltet Referenzprofile, Profilkombinationen, Toleranzen und Referenzergeb-nisse mit Toleranzgrenzen und ermöglicht so die Beurteilung der Zulässigkeit eines Mess- und Berechnungs-systems, unter Berücksichtigung von Zufalls- und Gitterfehlern des Messsystems. Sie gibt Berechnungs-grundsätze an, die einzuhalten sind, aber schreibt keine spezielle numerische Berechnungsmethode vor.
Sie legt keinen Grenzwert für die äquivalente Konizität fest und gibt keine Toleranzen für das Schienen-kopfprofil und das Radprofil an, um akzeptable Konizitätswerte zu erhalten.
Für andere Anwendungszwecke dieser Europäischen Norm (z. B. Simulation des Fahrzeugverhaltens) kann es nützlich oder erforderlich sein, weitergehende Verfahren zu verwenden. Diese Verfahren liegen außerhalb des Anwendungsbereiches dieser Europäischen Norm.
Für die Anwendung dieser Norm sind einige allgemeine Empfehlungen in Anhang I aufgeführt.

Applications ferroviaires - Méthode de détermination de la conicité équivalente

La présente Norme Européenne établit une procédure d'évaluation pour la détermination de la conicité équivalente. Un calcul de comparaison est spécifié pour l'obtention de résultats comparables sur une base cohérente pour la conicité équivalente, laquelle peut être calculée par différentes méthodes qui ne sont pas données dans la présente Norme Européenne. La présente Norme Européenne propose aussi des méthodes de calcul possibles. Des exemples de l'utilisation de la formule de Klingel (voir Annexe B) et d'une régression linéaire de la fonction r (voir Annexe C) sont inclus à titre informatif dans la présente Norme Européenne.
La présente Norme Européenne inclut des profils de référence, des combinaisons de profils, des tolérances et des résultats de référence avec des limites de tolérance, permettant à l’utilisateur d’évaluer l’acceptabilité d'un système de mesure et de calcul, en incluant les erreurs aléatoires et de grille inhérentes au système. Elle établit des principes de calcul qui doivent être suivis, mais n’impose aucune méthode de calcul particulière.
La présente Norme Européenne ne définit pas de limite pour la conicité équivalente et ne donne aucune tolérance pour les profils de rail et de roue, pour obtenir des résultats acceptables pour la conicité.
Pour les usages sortant du champ de la présente Norme Européenne (par exemple la simulation du comportement d'un véhicule), il peut être utile ou nécessaire d'utiliser des théories plus élaborées. Ces méthodes ne relèvent pas du domaine d'application de la présente Norme Européenne.
Pour l’application de la présente Norme Européenne, des recommandations générales sont données en Annexe I.

Železniške naprave - Metoda za ugotavljanje ustrezne koničnosti

Ta evropski standard vzpostavlja postopek vrednotenja za ugotavljanje ustrezne koničnosti. Opredeljen je primerjalni izračun za stalno doseganje primerljivih rezultatov ustrezne koničnosti, ki se lahko izračuna z različnimi metodami, ki niso navedene v tem evropskem standardu. Ta evropski standard predlaga tudi možne metode izračuna. V ta evropski standard so vključeni tudi informativni primeri uporabe Klingelove formule (glej Dodatek B) in linearne regresije funkcije Δr (glej Dodatek C). Ta evropski standard vključuje referenčne profile, kombinacije profilov, odstopanja in referenčne rezultate z dovoljenimi odstopanji, ki omogočajo uporabniku ocenjevanje sprejemljivosti sistema merjenja in izračunavanja, vključno s slučajnimi in mrežnimi napakami merilnega sistema. Določa načela izračunavanja, ki jih je treba upoštevati, vendar ne predpisuje točno določene metode numeričnega izračuna. Ta evropski standard ne opredeljuje omejitev ustrezne koničnosti in ne navaja odstopanja za profile tirnic in koles za doseganje sprejemljivih rezultatov koničnosti. Za namene, ki so zunaj obsega uporabe tega evropskega standarda (npr. za simulacijo obnašanja vozila), je koristno ali nujno uporabiti bolj zapletene teorije. Te metode niso predmet tega evropskega standarda. V Dodatku I je navedenih nekaj splošnih priporočil za uporabo tega evropskega standarda.
