V projektih za gradnjo in obnovo železnic, ali je treba upogniti tirnice, ni preprosto vprašanje DA ali NE, ampak ključno vprašanje, ki zahteva preudarno odločanje na podlagi večdimenzionalnih dejavnikov .
Line design requirements are the primary consideration. When the railway needs to pass through complex terrain such as urban blocks and mountainous areas, or set up turnouts and station curves, the bent rails can accurately match the line direction to ensure the smooth operation of the train. For example, due to underground space limitations, urban subway lines often require small radius curves, and the cold bending process can control the rail error to a very majhen domet; Medtem ko se velike pobočje in velike polmera gorskih železnic zanašajo na vroče upogibanje, da obdelajo tirnice z visoko trdostjo .
Operational performance and safety also affect decision-making. Bending rails can optimize the stress state of the train when it passes through a curve, reduce abnormal wear and impact force between wheels and rails, and reduce the risk of derailment. However, inappropriate bending processes or parameter deviations will lead to hidden dangers such as stress concentration and track Deformacija . Če ima začasna proga ali v rastlini nizke zahteve za hitrost teka in gladkost, lahko upogibanje železnic izpustite in rahlo prehod krivulje dosežemo s prilagajanjem razmika med spalnimi .
V skladu s scenarijem prijave tirnic je odločeno, ali je treba tirnice upogniti, da se zagotovi varnost delovanja vlaka . kot profesionalnega dobavitelja tirnic,Gnee Railvam lahko zagotovi strokovni nasvet .
