Numerična simulacija naleta vozila na cestno varnostno ograjo [Elektronski vir]
Vesenjak, Matej ; Ren, Zoran
Prispevek opisuje analizo jeklene cestne varnostne ograje, ki se že nekaj desetletij v nespremenjeni obliki uporablja na slovenskih cestah. Dosedanje raziskave so pokazale, da je togost celotne ...ograje prevelika. Namen raziskave je primerjava obstoječe konstrukcije z novo konstrukcijo, ki je sposobna absorbirati več energije trka. V ta namen so bile izvedene dinamične računalniške simulacije deformiranja modela odseka cestne varnostne ograje prinaletu vozila s programom LS-DYNA. Nova konstrukcija je bila testirana tudiz realnim naletom vozila na ograjo. Rezultati dinamičnih analiz so potrdili, da je trenutno uporabljena konstrukcija cestne varnostne ograje neprimerna, in da lahko z drugačno konstrukcijo zmanjšamo togost varnostne ograje in povečamo sposobnost absorpcije energije trka ter tako posredno pripomoremo k cestni varnosti.
