Dans un r\u00e9seau ferroviaire, le rail est soumis \u00e0 des contraintes m\u00e9caniques d’une intensit\u00e9 extr\u00eame :<\/p>

  • plusieurs dizaines de millions de cycles de charge,<\/p><\/li>

  • des pressions verticales sup\u00e9rieures \u00e0 10 tonnes par cm\u00b2,<\/p><\/li>

  • des efforts lat\u00e9raux incessants.<\/p><\/li><\/ul>

    \u00a0<\/p>

    Les aciers modernes (profils 50E6 ou 60E1), plus durs mais moins ductiles, d\u00e9veloppent sous ces sollicitations une zone \u00ab \u00e9crouie \u00bb en surface. Cette zone concentre des r\u00e9seaux de fissures qui, si elles ne sont pas trait\u00e9es, se propagent en profondeur. L’augmentation des charges transport\u00e9es et de la puissance de traction a amplifi\u00e9 le ph\u00e9nom\u00e8ne : aujourd’hui, pr\u00e8s de\u00a075 % des d\u00e9fauts recens\u00e9s sur le R\u00e9seau Ferr\u00e9 National<\/strong>\u00a0sont li\u00e9s \u00e0 la fatigue de contact et repr\u00e9sentent\u00a015 % des ruptures<\/strong>\u00a0ainsi que la majorit\u00e9 des retraits de rails.<\/p>

    \u00a0<\/p>

    Des pathologies bien identifi\u00e9es<\/strong><\/p>

    \u00a0<\/p>

    Fissures de type\u00a0head check<\/em>\u00a0, usure ondulatoire, squats, d\u00e9fauts de soudure, marques de ballast ou \u00e9caillages : ces d\u00e9fauts, s’ils ne sont pas trait\u00e9s, r\u00e9duisent la dur\u00e9e de vie du rail et d\u00e9gradent la s\u00e9curit\u00e9 et le confort de circulation.<\/p>

    \u00a0<\/p>

    Le fraisage : une r\u00e9ponse industrielle et \u00e9cologique<\/strong><\/p>

    \u00a0<\/p>

    En France, Vossloh utilise le train de fraisage SF03 W-FFS<\/strong>\u00a0con\u00e7u par Linsinger pour r\u00e9aliser un\u00a0reprofilage complet<\/strong>\u00a0des rails, sur lignes classiques comme sur lignes \u00e0 grande vitesse. Ce moteur est dot\u00e9 :<\/p>

    • d’un syst\u00e8me de mesure embarqu\u00e9 (d\u00e9tection du head-checking, analyse des ondes d’usure ondulatoire),<\/p><\/li>

    • d’un rugosim\u00e8tre pour v\u00e9rifier l’\u00e9tat de surface,<\/p><\/li>

    • d’outils de mesure manuels de profil et d’enl\u00e8vement de mati\u00e8re,<\/p><\/li>

    • et d’un syst\u00e8me d’aspiration int\u00e9gral des copeaux, garantissant l’absence de r\u00e9sidu en voie.<\/p><\/li><\/ul>

      \u00a0<\/p>

      \"\"<\/p>

      \u00a0<\/p>

      Les fraises, \u00e9quip\u00e9es de plaquettes au tungst\u00e8ne, retir\u00e9es entre\u00a00,4 et 1,8 mm<\/strong>\u00a0par passe dans un seul sens de progression, restituant un profil optimal et une surface liss\u00e9e. Depuis 2021,\u00a0pr\u00e8s de 100 postes<\/strong>\u00a0sont r\u00e9alis\u00e9s chaque ann\u00e9e pour SNCF R\u00e9seau, quand la Deutsche Bahn en commande\u00a0pr\u00e8s de 2000<\/strong>\u00a0sur un r\u00e9seau de taille comparable \u2014 preuve que le potentiel de pr\u00e9vention reste important.<\/p>

      \u00a0<\/p>

      Un maillon cl\u00e9 de l’\u00e9conomie circulaire<\/strong><\/p>

      Le fraisage ne se limite pas \u00e0 \u00ab r\u00e9parer \u00bb :<\/p>

      • il\u00a0ralentit la propagation des fissures<\/strong>\u00a0,<\/p><\/li>

      • il prolonge la dur\u00e9e de vie des rails<\/strong>\u00a0en \u00e9vitant des remplacements pr\u00e9matur\u00e9s,<\/p><\/li>

      • il r\u00e9duit les vibrations<\/strong>\u00a0, pr\u00e9servant l’int\u00e9grit\u00e9 des traverses, attaches et roues,<\/p><\/li>

      • optimiser l’utilisation de l’acier, notamment les extractions et \u00e9missions associ\u00e9es.<\/p><\/li><\/ul>

        \u00a0<\/p>

        Combin\u00e9 aux\u00a0contr\u00f4les par ultrasons<\/strong>\u00a0(qui d\u00e9tectent en amont les d\u00e9fauts internes), il permet une\u00a0maintenance pr\u00e9dictive<\/strong>\u00a0et un r\u00e9emploi maximal, coh\u00e9rents avec les objectifs de l’\u00e9conomie circulaire ferroviaire : moins de d\u00e9chets, plus de performance, et un cycle de vie des rails optimis\u00e9.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
