Ocena velikosti dinamičnih parametrov proge na osnovi meritev geometrije tiraŠturm, Janez ; Kranjec, PrimožČlanek zajema problematiko prometne varnosti na železnici z vidika vzdrževanja proge, da v največji možni meri glede na danost, izkjučimo dejavnik infrastrukture v smislu kvalitete proge in njenega ... vzdrževanja. Potrebe po meritvah dinamičnih parametrov se je pokazala pri uvebi vlakov z nagibno tehniko. Ti zaradi svoje konstrukcije izkoriščajo večje bočne pospeške in so s tem bliže mejnim vrednosti. Problem nastopi, kadar se na določenih odsekih pojavi kombinacija geometrijskih parametrov, ki sami zase ne presegajo mejnih vrednosti, upoštevajoč skupni vpliv pa prekoračijo dovoljene dinamične parametre. V letu 2002 je na mreži slovenskih prog začel meriti merilni voz UFM120. Voz zajema geoemtrijo proge na brezkontakten način.Omogočena je uporaba t.i. surovih podatkov za kasnejšo obdelavo, ki omogoča določitev dinamičnih parametrov proge, ki so bili do sedaj izključno merjeni in s tem podvrženi vplivom lastnosti vozila na meritev. Predlagana obdelava povečuje verjetnost odkritja mest, kjer nastopi kritična kombinacija geometrijskih parametrov in s tem povečuje varnost železniškega prometa. V članku je obdelan pristop k reševanju takega problema. Predstavljena je teorija, ki smo jo razvili v ta namen ter vse zakonitosti. Opisan je tudi predlog implementacije ter teorije na mreži slovenskih prog ter prednosti in slabosti oz. nepopolnosti postopka.Source: Zbornik referatovType of material - conference contributionPublish date - 2002Language - slovenianCOBISS.SI-ID - 25345797
