Kodiranje šinskih defekata prema IRS 70712
Codiing system for rail defects in accordance with IRS 70712
Projekat: Ministarstvo prosvete, nauke i tehnološkog razvoja Republike Srbije (institucija: Univerzitet u Beogradu, Građevinski fakultet) (MPNTR - 451-03-68/2020-14/200092)
Ključne reči: železnica; održavanje; šinski defekat; sistem kodiranja; zamor šinskog čelika pri kotrljanju
Sažetak
Šinski defekti usled zamora čelika pri kotrljanju točkova dobili su značajno mesto u Priručniku za šinske defekte (Handbook of Rail Defects) u okviru UIC Code 712 iz 2002. godine. U radu je prikazan sistem za kodiranje i klasifikaciju šinskih defekata prema UIC preporuci IRS 70712 iz 2018. godine. Prikazana klasifikacija još uvek ne obuhvata sve poznate defekte usled zamora šinskog čelika pri kotrljanju (npr. stud i belgrospi defekti). Preporučuje se da Upravljač infrastrukture dopuni Priručnik za šinske defekte tipovima defekata koje uočava na mreži kojom upravlja. Autori daju preporuku koje podatke treba da sadrži baza šinskih defekata, kako bi se pratio razvoj defekata, preduzete mere i njihova efikasnost i kako bi se omogućila razmena statističkih podataka o defektima na međunarodnom nivou.
Abstract
Rail defects due to the rolling contact fatigue have a significant place in the Handbook of Rail Defects in the framework of UIC Code 712 in 2002. The paper presents the system for coding and classification of rail defects according to UIC recommendation IRS 70712 in 2018. The presented classification does not cover all known defects due to the rolling contact fatigue (e.g. stud and belgrospi defects). It is recommended that Infrastructure Manager should supplement the Handbook of Rail Defects with the types of defects noticed on its railway network. The authors recommend information that should be included in the database of rail defects, in order to monitor the development of defects, taken measures and their efficiency, as well as to enable the exchange of statistical data on rail defects at the international level.
