In terms of preventing vehicles from veering off the road, a road-safety barrier should redirect the impacting vehicle back onto the road. In the process of doing so it should absorb as much of the vehicle's kinetic energy as possible through its deformation, so reducing the deceleration of the vehiclećs occupants. This paper considers a computer simulation of a truck's impact on a steel road-safety barrier. Parametric computer simulations were used to evaluate the different additional safety elements of the road-safety barrier. The dynamic finite-element explicit code LS-DYNA was used for this purpose. The computer simulations prove that the analyzed road-safety barrier design is strong enough to retain and redirect the truck back onto the roadway. Appropriately, the high absorption of the impacting vehicle's kinetic energy through the safety-barrier deformation is observed at the same time, which indicates a reduction in a vehicle's deceleration, and with that, a higher safety level for the vehicle's occupants</dc:description><dc:description xml:lang="sl">Cestno varnost lahko izboljšamo s postavitvijo cestnih varnostnih ograj, ki preprečujejo udeležencem cestnega prometa vstop v nevarna območja. Za dvig stopnje varnosti morajo biti cestne varnostne ograje oblikovane tako, da pri naletu vozila le-to preusmerijo nazaj na cestišče. Med preusmerjanjem vozila morajo s svojo deformacijo absorbirati čim večjo količino kinetične energije, da se zmanjšajo pojemki potnikov v vozilu. V prispevku je predstavljena računalniška simulacija naleta tovornega vozila ob cestno varnostno ograjo. Izvedene so bile parametrične računalniške analize za oceno primernosti različnih dodatnih elementov varnostne ograje. Za izvajanje eksplicitnih dinamičnih analiz je bil uporabljen program LS-DYNA. Računalniske simulacije dokazujejo, da je nosilnost analizirane ograje dovolj velika, da tovornjak zadrži in preusmeri nazaj na cestišče. Hkrati pa se pokaze tudi ustrezno visoka stopnja akumulacije kinetične energije vozila v obliki deformacije cestne varnostne ograje, kar zmanjša pojemke vozila in se kaže v povečani stopnji varnosti za potnike v vozilu</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-XZSV1B23"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-XZSV1B23" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-XZSV1B23/99b82646-0f2f-4264-acf6-8797b38ded23/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-XZSV1B23/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-XZSV1B23" /></ore:Aggregation></rdf:RDF>
