Le meulage des rails permet d'\u00e9viter l'accumulation dangereuse de la fatigue des contacts de roulement et de r\u00e9duire le bruit de roulement pour les communaut\u00e9s riveraines. James Abbott \u00e9value certains d\u00e9veloppements et aspects significatifs de ce domaine important de notre industrie.<\/p>

\"\"<\/p><\/div>

La fraiseuse SFU 04 de Schweerbau<\/p><\/div>

L'accident de Hatfield au Royaume-Uni en 2000 a \u00e9t\u00e9 un signal d'alarme pour les administrations ferroviaires du monde entier. Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que le d\u00e9raillement d'un train express de voyageurs, qui a entra\u00een\u00e9 la mort de plusieurs d'entre eux, \u00e9tait d\u00fb \u00e0 la fatigue de contact de roulement (FCR), dans laquelle de minuscules fissures dans le champignon du rail s'\u00e9tendent vers le bas dans le corps du rail, ce qui finit par provoquer une rupture.<\/p>

Les statistiques produites par la Federal Railroad Administration aux \u00c9tats-Unis sugg\u00e8rent que le FCR a \u00e9t\u00e9 fortement impliqu\u00e9 dans 122 d\u00e9raillements et qu'il pourrait avoir \u00e9t\u00e9 un facteur contributif dans 160 autres incidents au cours de la p\u00e9riode 1995-2002.<\/p>

Gr\u00e2ce \u00e0 de telles statistiques, la FCR est largement accept\u00e9e comme un probl\u00e8me qui doit \u00eatre g\u00e9r\u00e9 par les administrations ferroviaires. Ne rien faire n'est pas une option : le Royaume-Uni a cess\u00e9 les op\u00e9rations de meulage des rails quelques ann\u00e9es avant l'accident, et il est d\u00e9sormais admis que cette d\u00e9cision n'\u00e9tait pas judicieuse. Le meulage rase la surface sup\u00e9rieure du rail, \u00e9liminant les fissures avant qu'elles n'aient une chance de se propager vers le bas dans l'\u00e2me et pr\u00e9venant ainsi les ruptures de rail.<\/p>

\u00a0<\/div>

Une \u00e9tude de la Commission europ\u00e9enne sugg\u00e8re que la gestion des FCR est un exercice co\u00fbteux, avec un chiffre de 300 millions d'euros mentionn\u00e9 pour la gestion du probl\u00e8me chaque ann\u00e9e sur le r\u00e9seau ferroviaire europ\u00e9en. Ce montant comprend les activit\u00e9s d'inspection, de meulage des rails, de remplacement des rails et de r\u00e9paration des soudures, ainsi que les inconv\u00e9nients li\u00e9s aux retards des trains et aux d\u00e9raillements lorsqu'ils se produisent.<\/p>

Il est clair que ce probl\u00e8me m\u00e9rite que l'on s'y attarde et que les administrations ferroviaires doivent se tenir au courant des derni\u00e8res technologies si elles veulent minimiser le co\u00fbt de la FCR.<\/p>

Gestion du FCR<\/h2>

Dans une \u00e9tude r\u00e9alis\u00e9e pour le Conseil national de la recherche du Canada, Eric Magel, Peter Sroba, Kevin Sawley et Joe Kalousek affirment que \u201cde nombreux facteurs interagissent pour influencer la FCR\u201d, citant notamment la duret\u00e9 des rails, les profils d\u00e9taill\u00e9s des roues et des rails et la dynamique lat\u00e9rale et longitudinale de l'essieu. Mais ils ajoutent que \u201cla FCR est particuli\u00e8rement sensible aux profils des roues et des rails et que des profils inappropri\u00e9s ou non contr\u00f4l\u00e9s peuvent compl\u00e8tement masquer les effets de la m\u00e9tallurgie\u201d.\u201d<\/p>

Les chercheurs ajoutent qu'au Royaume-Uni, l'exp\u00e9rience g\u00e9n\u00e9rale a montr\u00e9 que les aciers \u00e0 haute r\u00e9sistance sont plus enclins \u00e0 former des FCR - \u201cune constatation qui peut s'expliquer par la section de rail \u00e0 haute contrainte utilis\u00e9e et l'incapacit\u00e9 des aciers durs \u00e0 s'user ou \u00e0 s'\u00e9couler vers une forme \u00e0 plus faible contrainte\u201d. L'exp\u00e9rience britannique montre \u00e9galement que si le rail est initialement meul\u00e9 pour obtenir une forme moins contrainte, il r\u00e9siste beaucoup mieux \u00e0 la FCR que les aciers plus tendres. Cela souligne l'importance du meulage initial des rails.<\/p>

Les chercheurs canadiens expliquent l'importance du \u2018taux d'usure magique\u2019, c'est-\u00e0-dire le processus qui consiste \u00e0 enlever juste ce qu'il faut de la surface du rail pour emp\u00eacher la propagation des fissures. \u201cDans les voies avec FCR, le taux d'usure naturelle doit \u00eatre compl\u00e9t\u00e9 par un meulage pour atteindre le taux d'usure magique\u201d, affirment-ils. Le taux d'usure magique est g\u00e9n\u00e9ralement plus \u00e9lev\u00e9 dans les courbes que sur les voies droites, l'exp\u00e9rience nord-am\u00e9ricaine sur les lignes \u00e0 fort tonnage montrant que le rail inf\u00e9rieur dans les courbes doit \u00eatre soigneusement g\u00e9r\u00e9 par meulage pour atteindre le taux d'usure magique.<\/p>

Speno \u00e0 la pointe de l'innovation<\/h2>

Il y a quelques ann\u00e9es, Speno International a commenc\u00e9 \u00e0 \u00e9tudier la possibilit\u00e9 de d\u00e9tecter les fissures de fatigue superficielle pendant le meulage. Un d\u00e9veloppement conjoint avec Deutsche Bahn AG a abouti \u00e0 un syst\u00e8me d'enregistrement capable de mesurer la densit\u00e9 des d\u00e9fauts et la profondeur des dommages.<\/p>

Apr\u00e8s des essais intensifs sur piste avec un prototype, six machines de meulage Speno ont \u00e9t\u00e9 \u00e9quip\u00e9es du \u2018Headcheck Grinding Scanner\u2019 de la soci\u00e9t\u00e9. Ce syst\u00e8me permet aux op\u00e9rateurs de v\u00e9rifier la r\u00e9duction des d\u00e9fauts de fatigue lors de chaque passage de meulage et de documenter le r\u00e9sultat obtenu en ce qui concerne l'enl\u00e8vement du m\u00e9tal de la surface du rail fatigu\u00e9. Le syst\u00e8me est entr\u00e9 en service commercial aupr\u00e8s de plusieurs chemins de fer europ\u00e9ens, notamment en Autriche, en France, aux Pays-Bas et en Pologne.<\/p>

L'arriv\u00e9e du \u2018Headcheck Grinding Scanner\u2019 est la derni\u00e8re d'une longue liste d'innovations de Speno. Dans les ann\u00e9es 1980, l'entreprise a introduit un train de meulage avec des moteurs de meulage inclinables t\u00e9l\u00e9command\u00e9s. Cette innovation a \u00e9t\u00e9 suivie par la premi\u00e8re rectifieuse d'aiguillage, le premier \u00e9quipement de mesure embarqu\u00e9 pour la section transversale des rails et l'introduction de syst\u00e8mes de d\u00e9poussi\u00e9rage.<\/p>

Speno travaille avec les gestionnaires d'infrastructures ferroviaires sur les moyens de traiter les d\u00e9fauts et les probl\u00e8mes sp\u00e9cifiques g\u00e9n\u00e9r\u00e9s par le trafic ferroviaire intense. L'entreprise participe au projet de recherche europ\u00e9en \u2018Innotrack\u2019, qui rassemble l'exp\u00e9rience et le savoir-faire de plusieurs organisations ferroviaires et de l'industrie.<\/p>

Speno pr\u00e9side le projet de travail 4.5 \u2018Maintenance des rails\u2019 dans le cadre du programme Innotrack. Des informations sont pr\u00e9par\u00e9es \u00e0 l'intention des gestionnaires d'infrastructure sur la mani\u00e8re d'\u00e9tablir une strat\u00e9gie de maintenance appropri\u00e9e pour lutter contre la fatigue des contacts de roulement, y compris les profils de rail cibles sugg\u00e9r\u00e9s.<\/p>

\"\"<\/p>

Les 2 trains broyeurs synchronis\u00e9s xRR 48 M de Speno en service en France<\/p><\/div>

Speno con\u00e7oit, construit et exploite des trains de meulage depuis 40 ans. L'entreprise affirme que ses 30 unit\u00e9s de meulage de rails en service en Europe en 2009 constituent de loin la plus grande flotte de trains de meulage sous un m\u00eame toit. \u201cLa longue exp\u00e9rience de Speno en mati\u00e8re de conception, de fabrication et d'exploitation de trains de meulage permet d'obtenir d'excellentes performances, combinant un rendement \u00e9lev\u00e9 par \u00e9quipe et une qualit\u00e9 constamment contr\u00f4l\u00e9e jour apr\u00e8s jour.<\/p>

Speno reconna\u00eet que les travaux de meulage de routine comprennent aujourd'hui<\/p>

  • Meulage initial des nouveaux rails, meulage cyclique pr\u00e9ventif et correctif<\/li>
  • Application de profils sp\u00e9ciaux pour r\u00e9duire l'usure des rails hauts, att\u00e9nuer la fatigue des coins d'\u00e9cartement et am\u00e9liorer le comportement de roulement, y compris l'\u00e9largissement de l'\u00e9cartement.<\/li>
  • Broyage anti-bruit pour minimiser le bruit g\u00e9n\u00e9r\u00e9 par le trafic ferroviaire<\/li><\/ul>

    L'ex\u00e9cution du broyage en un seul passage \u00e0 l'aide de machines robustes est actuellement mise en \u0153uvre sur les lignes \u00e0 grande vitesse. \u201cUn personnel exp\u00e9riment\u00e9 et comp\u00e9tent est tr\u00e8s important\u201d, d\u00e9clare Speno. Selon l'entreprise, l'astuce ne consiste pas seulement \u00e0 enlever une certaine quantit\u00e9 de m\u00e9tal en une seule passe, mais aussi \u00e0 garantir un taux d'enl\u00e8vement de m\u00e9tal minimal.<\/p>

    Nouveau v\u00e9hicule de fraisage Linsinger pour les SLR<\/h2>

    Le train de fraisage de rails SF 01 F de l'entreprise autrichienne Linsinger est \u00e9galement destin\u00e9 au secteur des trains l\u00e9gers. Il a \u00e9t\u00e9 pr\u00e9sent\u00e9 pour la premi\u00e8re fois il y a un an, au d\u00e9but de l'ann\u00e9e 2008, et l'entreprise affirme avoir obtenu de tr\u00e8s bons r\u00e9sultats sur des syst\u00e8mes de m\u00e9tro l\u00e9ger en Asie.<\/p>

    Le concept de profilage du rail par fraisage en un seul passage est d\u00e9j\u00e0 bien connu gr\u00e2ce aux machines pr\u00e9c\u00e9dentes de Linsinger, et la SF 01 F s'appuie sur cette exp\u00e9rience. Linsinger affirme que sa technologie de fraisage des rails combine le fraisage et le meulage des rails en une seule op\u00e9ration avec un haut degr\u00e9 de pr\u00e9cision et de performance, ajoutant que les syst\u00e8mes de chemins de fer l\u00e9gers peuvent obtenir une r\u00e9duction significative des co\u00fbts d'entretien gr\u00e2ce \u00e0 l'utilisation de cette technologie.<\/p>
