Analysis of vehicle behaviour in a test procedure with vertical excitation

Zbog ograničavanja brzine vožnje vozila i povećavanja sigurnosti prometovanja, na ceste se postavljaju različite prepreke za smirivanje prometa. U radu je analizirano ponašanje vozila prilikom prelaska preko prepreka za smirivanje prometa. Prikazano je zakonsko uređenje područja signalizacije i opreme za smirivanje prometa kao i prikaz i opisi različitih simulacijskih modela koji se koriste u analizi dinamike vozila u ispitnoj proceduri s vertikanom pobudom. Simulacije su izrađene u programskom paketu CarSim. Odabran je model vozila, izrađeni oblici prepreka te mijenjani parametri vozila (masa, dimenzije kotača, krutost opruge ovjesa). Rezultati su prikazani kroz dijagrame.Various traffic calming devices are placed on the road for the sake of limiting the speed of the vehicle and increasing traffic safety. The behaviour of the vehicle crossing traffic calming obstacles is analysed in this thesis. The traffic signs and traffic calming devices regulations, as well as description of simulation models used in the analysis of vehicle dynamics in the test procedure with vertical excitation are shown. The simulations are made in CarSim. The model of the vehicle is selected, obstacle shapes are made, and vehicle parameters (mass, wheel dimensions, suspension spring stiffness) are changed. The results are shown in diagrams
