Abstract

ǂV ǂprispevku je prikazan postopek računalniško podprtega simuliranja elasto-plastičnega deformiranja naprave za zaščito pred podletom od zadaj, ki omogoča oceno konstrukcijske rešitve pred homologacijo. Homologacijski pravilnik ECE R 58 namreč predpisuje način preskušanja zaščitne naprave, dopušča pa tudi, da zaščitno napravo poleg praktičnega preskušanja preverimo tudi z računalnikom. Prispevek prikazuje nadaljni razvoj postopka elasto-plastičnega računalniškega simuliranja z metodo končnih elementov, ki smo ga predstavili na IAT 99 [5]. Rezultati elasto-plastične analize obetajo možnost optimiranja zaščitne naprave v fazi konstruiranja brez izvedbe praktičnih preskusov. Računalniško simuliranje tudi precej poceni postopek homologacije novih naprav.

Secondary title:	Elasto-plastic deformation analysis of a rear-underrun protection device for load-carrying vehicles
Secondary abstract:	ǂThe ǂpaper describes a procedure for simulating the elasto-plastic behaviour of a rear-underrun protection device (RUPD), which can be used to estimate whether the design fulfils the ECE R 58 regulation. This regulation prescribes practical device testing, but also allows a computational safety inspection of the protection device. The paper also includes the development of the elasto-plastic computational simulation using the finite-element method that was presented at IAT 99 [5]. The results of the elasto-plastic analysis simulations load to the conclusion that this method can be used to optimize the RUPD in the design process without the need for practical testing. Computational simulation also reduces the cost of the approval without the need for practical testing. Computational simulation also reduces the cost of the approval procedure.
