dc.description.abstractInfrastructure Manager should monitor the wear of rail steel and development of defects on the running surface of rails in order to accomplish efficient lifecycle management of rails. According to the collected statistical data on wear as a function of accumulated load, it is possible to create mathematical models of rail steel wear and removal of surface defects by wear, milling and grinding of specific track sections. The paper presents the combined model of the vertical wear and cyclical grinding of the rail profile 60E1. Developed model provide the basis for com­parison of different cyclical grinding strategies from the aspect of rail lifecycle and matching the cycles of integral maintenance of ballasted track. Length of maintenance cycle for each element of superstructure was assumed according to the experience of representative European railway managers.en
dc.description.abstractZa efikasno upravljanje životnim vekom šine, Upravljač infrastrukture treba da prati habanje šinskog čelika i razvoj defekata na voznoj površi glave šine tokom vremena. Na osnovu prikupljenih statističkih podataka o habanju i napredovanju prslina u funkciji akumuliranog saobraćajnog opterećenja, moguće je formiranje matematičkih modela trošenja šinskog čelika usled habanja, glodanja i brušenja na karakterističnim sekcijama koloseka. U radu je prikazan model vertikalnog trošenje šine 60E1 usled vertikalnog habanja i cikličnog brušenja. Na osnovu formiranog modela moguće je poređenje različitih strategija cikličnog brušenja šine sa stanovišta njenog životnog veka i uklapanja u cikluse integralnog održavanja koloseka sa betonskim pragovima u zastoru od tucanika. Pretpostavljene su dužine ciklusa održavanja elemenata konstrukcije gornjeg stroja prema iskustvima razvijenih evropskih železničkih uprava.sr
