Problematika železniških pragov

projektna naloga

Abstract

V projektni nalogi so predstavljeni rezultati sinhronizacije dveh različnih meritev (merilne tehtnice ter meritve kinematičnih in mehanskih parametrov odziva praga). Raziskava predstavlja majhen prispevek k CRP projektu, ki se ukvarja z izdelavo inovativnega železniškega praga. Ukvarjali smo se z vrednotenjem zunanje obtežbe na enem merilnem mestu na progi Divača−Koper. Končni rezultat raziskave je grafična predstavitev sinhroniziranih rezultatov dveh meritev. Ugotovili smo, da se sinhronizirane meritve ujemajo s splošnimi zakonitostmi dinamike konstrukcij pri diskretnih sistemih z več prostostnimi stopnjami, kjer maksimumi količin ne nastopajo vsi v istem času. Posledično največja obtežba na prag nastopi v situacijah, ko obravnavani prag prevzame večino obtežbe osi.

Secondary title:	A problematic of railway sleepers
Secondary abstract:	In this project work the results of synchronization of two different measurements are presented, i.e. measurement using measuring scales, and measurement of kinematic and mechanical parameters of the railway sleeper response. The research represents a small contribution to the CRP project, which deals with the production of an innovative railway sleeper. We were engaged in the evaluation of external load at one measuring point on the railway line Divača-Koper. We gave the final result of the research as a graphical presentation of the synchronized results of the two measurements. We found that synchronized measurements correspond to the general laws of structural dynamics of discrete systems with multi degrees of freedom, where the maxima of quantities do not occur simultaneously. Consequently, the maximum load on the railway sleeper occurs at the moment when it takes over the majority of the axle load.
