Aux premi\u00e8res heures du 19 novembre, pr\u00e8s de la gare de Lashihai sur la ligne ferroviaire Yunnan-Lijiang-Shangri-La, \u00e0 une altitude de 2 487 m\u00e8tres, une nouvelle g\u00e9n\u00e9ration de machine de bourrage et de stabilisation continue de fabrication nationale, de couleur jaune et bleue, a progress\u00e9 de mani\u00e8re r\u00e9guli\u00e8re le long d'une longue pente raide de 28,5 \u2030, effectuant avec pr\u00e9cision des tests op\u00e9rationnels continus et \u00e9tape par \u00e9tape. Ce test de performance sp\u00e9cialis\u00e9 cible les conditions complexes de haute altitude et de pentes raides, marquant la premi\u00e8re fois que les machines intelligentes de maintenance des voies ferr\u00e9es \u00e0 grande \u00e9chelle de nouvelle g\u00e9n\u00e9ration d\u00e9velopp\u00e9es ind\u00e9pendamment par la Chine rel\u00e8vent les principaux d\u00e9fis de la ligne ferroviaire Lijiang-Shangri-La.<\/p>

\"\"<\/p>

Ces derni\u00e8res ann\u00e9es, avec l'avancement continu de la construction ferroviaire dans plusieurs r\u00e9gions de plateau \u00e0 travers la Chine, les environnements de haute altitude avec des pentes raides et variables sont devenus de plus en plus courants. Cela a donn\u00e9 naissance \u00e0 une nouvelle g\u00e9n\u00e9ration de machines intelligentes de grande envergure pour l'entretien des voies, d\u00e9velopp\u00e9es avec des droits de propri\u00e9t\u00e9 intellectuelle enti\u00e8rement ind\u00e9pendants en Chine. Apr\u00e8s ses d\u00e9buts chez CRCC Equipment en d\u00e9cembre 2024 et sa premi\u00e8re apparition sur les chemins de fer du Yunnan en juin 2025, cette s\u00e9rie de tests se concentre sur la pente extr\u00eame de 28,5 \u2030 et les sections pr\u00e9sentant des variations de pente allant de 12 \u2030 \u00e0 28,5 \u2030 le long de la ligne ferroviaire Lijiang-Shangri-La. R\u00e9alis\u00e9s au cours de quatre fen\u00eatres de maintenance, les essais \u00e9valuent de mani\u00e8re exhaustive les op\u00e9rations continues et \u00e9tape par \u00e9tape dans des sc\u00e9narios impliquant des mont\u00e9es, des descentes et des pentes variables.<\/p>

\"\"<\/p>

\u201c Il ne s'agit pas seulement d'une \u00e9valuation compl\u00e8te des performances de l'\u00e9quipement, mais aussi d'une \u00e9tape cruciale dans la collecte de donn\u00e9es cl\u00e9s pour les op\u00e9rations automatiques \u00e9tape par \u00e9tape des machines de bourrage d'aiguillages ult\u00e9rieures \u201d, a expliqu\u00e9 Yang Dong, directeur adjoint de l'atelier d'entretien des voies n\u00b0 1 du d\u00e9p\u00f4t de machines d'entretien des voies de Kunming, qui d\u00e9pend du groupe China Railway Kunming. Pendant les op\u00e9rations, les machines d'entretien \u00e0 grande \u00e9chelle de nouvelle g\u00e9n\u00e9ration exploitent pleinement les avantages fondamentaux de leur syst\u00e8me de traction \u00e0 moteur \u00e9lectrique \u00e0 combustion interne, surmontant ainsi les probl\u00e8mes de \u201c mal d'altitude \u201d auxquels sont confront\u00e9es les machines d'entretien traditionnelles dans les r\u00e9gions de haute altitude. Leur syst\u00e8me d'analyse et de contr\u00f4le intelligent identifie automatiquement les param\u00e8tres de pente et ajuste les param\u00e8tres op\u00e9rationnels en temps r\u00e9el avec pr\u00e9cision, ce qui permet de r\u00e9soudre efficacement le probl\u00e8me critique du contr\u00f4le de la vitesse sur les longues pentes raides et d'am\u00e9liorer \u00e0 la fois l'efficacit\u00e9 op\u00e9rationnelle et le contr\u00f4le de la qualit\u00e9.<\/p>

\"\"<\/p>

Afin de garantir le bon d\u00e9roulement des essais, China Railway Kunming Group a mis en place une \u00e9quipe sp\u00e9cialis\u00e9e. Chaque aspect, de l'inspection des voies \u00e0 la pr\u00e9paration des v\u00e9hicules en passant par l'assistance d'urgence, a \u00e9t\u00e9 rigoureusement contr\u00f4l\u00e9. Face \u00e0 des conditions difficiles telles que les variations importantes d'altitude et l'air rar\u00e9fi\u00e9, le personnel op\u00e9rationnel a fait preuve d'un sens aigu des responsabilit\u00e9s et de sa mission, garantissant ainsi la s\u00e9curit\u00e9 et le contr\u00f4le de l'ensemble du processus d'essai.<\/p>

\u201c Apr\u00e8s six mois d'essais sur le terrain, la nouvelle g\u00e9n\u00e9ration de machines d'entretien des voies \u00e0 grande \u00e9chelle s'est parfaitement adapt\u00e9e aux exigences d'entretien de divers environnements complexes. Qu'il s'agisse de conditions de manque d'oxyg\u00e8ne en haute altitude ou de d\u00e9fis op\u00e9rationnels pos\u00e9s par des pentes raides, elle fonctionne avec aisance \u201d, a d\u00e9clar\u00e9 He Jinquan, ing\u00e9nieur en recherche et d\u00e9veloppement chez CRCC Equipment.<\/p>

\"\"<\/p>

Le succ\u00e8s des essais de gradient sur la ligne ferroviaire Lijiang-Shangri-La confirme pleinement l'efficacit\u00e9 op\u00e9rationnelle et la s\u00e9curit\u00e9 des \u00e9quipements intelligents de nouvelle g\u00e9n\u00e9ration fabriqu\u00e9s localement dans des conditions de travail complexes. Il marque \u00e9galement une avanc\u00e9e technologique pour les machines d'entretien des voies ferr\u00e9es \u00e0 grande \u00e9chelle en Chine, \u00e9largissant leurs capacit\u00e9s des op\u00e9rations sur voies plates aux environnements difficiles des plateaux. Cette avanc\u00e9e permettra de fournir des solutions d'entretien plus efficaces et plus fiables pour les chemins de fer dans les r\u00e9gions de plateau.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
