Abstract

Zbog provođenja tipskih ispitivanja razine buke uzrokovane kretanjem tračničkih vozila po voznoj površini tračnica provedena je kontrola stanja gornjeg ustroja kolosijeka na ispitnom poligon dviju dionica: kolosijek M101 „Državna granica – Savski Marof – Zagreb Glavni kolodvor“ na lokaciji „Brdovec“ i kolosijek M104 „Novska – Tovarnik - Državna granica“ na lokaciji „Lađevac“. Radi validnosti rezultata dobivenih mjerenjem buke prilikom prelaska tračnički vozila potrebno je izmjeriti stanje geometrije kolosijeka. Na ispitnim poligonima izmjerena je ravnost vozne površine. Ispitivanja su provedena prema normi HRN EN ISO 3095. Dobiveni rezultati analizirani su u danjem radu. Opisana je povezanost hrapavosti površine tračnica i nastanak buke prilikom prolaska tračničkih vozila. Dobiveni rezultati istraživanja ukazuju nam na potrebu redovitih kontrola stanja gornjeg ustroja kolosijeka što bi rezultiralo smanjenje emisije buke u okolišu i smanjilo troškove održavanja tračnički vozila i kolosijeka.

Abstract (english)

In order to carry out typical noise measurements of the noise level caused by the movement of rail vehicles on the rails running surface, a control of geometry state of the railway track was carried out at the test site of two sections: track M101 "Dražavna granica - Savski Marof - Zagreb Main Station" at the location "Brdovec" and track M104 "Novska - Tovarnik - National border" at the location "Lađevac". For the validity of the results obtained by measuring the noise when crossing railway vehicles, it is necessary to measure the condition of the track geometry. The flatness of the driving surface was measured at the test sites. The tests were carried out according to the HRN EN ISO 3095 standard. The obtained results were analyzed in this paper. The connection between the roughness of the rail surface and the generation of noise during the passage of rail vehicles is described. The obtained results of the research indicate the need for regular checks of the condition of the upper track structure, which would result in a reduction of noise levels in the environment and reduce the maintenance costs of rail vehicles and tracks.
