Abstract

V diplomski nalogi je prikazan potek validacije numeričnega modela vozila TB11. To je osebno vozilo teže 900 [kg]. Namen uporabe modela je simuliranje obnašanja cestnih varnostnih ograj pri trku vozila. Osnovni model vozila je bil povzet po javno dostopnih knjižnicah. Modelu vozila je bila spremenjena njegova geometrija, ter lastnosti njegovih komponent. Njegovo obnašanje in lastnosti so bile preizkušene s pomočjo simulacij. Te so bile izvedene s programom Ls-Dyna, za pripravo modelov pa je bil uporabljen program Ls-Prepost. Rezultati simulacij so bili ovrednoteni. Na njihovi podlagi so bile izvedene nadaljnji popravki modela vozila. Po zaključenih simulacijah je bil izdelan model vozila, katerega gibanje je primerljivo z gibanjem realnega vozila. Nastali model je primeren za simuliranje trka vozila v cestno varnostno ograjo. S pomočjo teh simulacij se zmanjša število potrebnih simulacij pri razvoju novih cestnih varnostnih ograj.

Secondary title:	Validation of TB11 vehicle computational model for testing of road safety barriers
Secondary abstract:	This diploma shows the progress of the validation of the numerical model of vehicle TB11. This is a personal vehicle weight of 900 [kg]. The purpose of the model is to simulate the behaviour of road safety barriers during a vehicle crash. The basic model of the vehicle was taken from publicly accessible libraries. Model vehicle amended its geometry and properties of its components. His behaviour and properties have been tested through simulations. These were made by LS-Dyna, for the preparation of models has been used Ls-Prepost. The simulation results were evaluated. On their basis were carried out further corrections of the model. Upon completion of the simulations was constructed model of the vehicle, which movement can be compared with real vehicles. The resulting model is suitable for simulating the collision of the vehicle in a road safety barrier. With the help of these simulations reduces the number of required simulations in developing new road safety barriers.
