Abstract:Prispevek podaja osnove sedanjega in možnosti novega numeričnega izračuna naprave za zaščito pred podletom od zadaj, ki pride v poštev pri homologaciji motornih tovornih vozil. Ustreznost zaščitne naprave se preverja glede na predpis ECE R 58, ki podaja natančna merila, katerim mora ustrezati konstrukcija naprave in njeno obnašanje pod obremenitvijo. Predpis dopušča možnost računskega preverjanja ustreznosti zaščitne naprave, od česar je odvisna raziskava možnosti računalniškega simuliranja obnašanja naprave pod obremenitvijo. Prispevek podaja osnovna izhodišča in postopke pravilnega računalniškega simuliranja, ki temelji na metoddi končnih elementov. V tej zgodnji fazi raziskav je v računalniških simuliranjih obravnavan le primer elastičnega deformiranja analizirane zaščitne naprave, ki je tudi eksperimentalno preskušena. Dobro ujemanje numeričnih in eksperimentalnih rezultatov potrjuje primernost izbrane simulirne metode za preverjanje ustreznosti zaščitne naprave.

Title:Computational safety inspection of a rear underrun protection device for loadcarrying vehicles
Abstract:This paper describes the fundamentals of the present situation and explores the possibilities of new computational safety inspection procedures for rear underrun protection devices (RUPDs), which are essential for the approval o loadcarrying vehicles. A RUPD is required to comply with the ECE R 58 regulation, which provides strict requirements in terms of device design and its behaviour under loading. The regulation allows for computational safety inspection of the protection device, which has prompted research into exporing the possibilities for computational simulation of RUPD behaviour under loading. This paper describes the conditions and procedures for proper computational simulations, which are based on the FEM. At this early stage of research only the elastic response of the studied RUPD is considered in the computational analyses. The studied safety device has also been experomentally tested. Reasonably good agreement of computational and experimental results leads to the conclusion that computational analyses can be used for inspection of a RUPD.
