Računalniško podprto konstruiranje cestne varnostne ograje = Computer-aided design of a road restraint barrierVesenjak, Matej ; Ren, ZoranCestne varnostne ograje na javnih cestah so namenjene za preprečitev zleta vozila s cestisča ali preboja na nasprotni vozni pas. Evropski standard SIST EN 1317 podaja merila, ki jih mora ograja ... izpolnjevati pod testno obremenitvijo Dosedanja praktična opažanja kažejo, da je sedanji distančnik cestne varnostne ograje, ki se uporablja v Republiki Sloveniji, pretog. To ima za posledico prevelike pojemke pri naletu osebnega vozila. Zato je določitev primerne oblike distančnika izrednega pomena za povečanje varnosti udeležencev v prometu. Namen raziskave je oblikovanje novega distančnika, ki se bo nadzorovano deformiral in bo zmozen povečati akumulacijo deformacijske energije pri naletu vozil. V ta namen so z uporabo metode končnih elementov analizirane različne oblike distančnikov. V začetni fazi razvoja je analizirana togost različnih oblik distančnikov z navidez statično elasto-plastično analizo trirazsežnega modela odseka varnostne ograje. Ugotovljeno je, da ima sedanji distančnik zelo veliko togost in da so distančniki novih oblik zmozni večje, nadzorovane elasto-plastične deformacije pri naletu vozil.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 49, št. 10, 2003, str. 509-519)Type of material - article, component partPublish date - 2003Language - slovenian, englishCOBISS.SI-ID - 6945051
