20.500.12556/RUL-139759 Simulacija škropljenja blata po avtomobilskih vratih Simulation of mud soiling on car doors Cilj naloge je bil simulirati škropljenje blata na avtomobilskih vratih. Simulacije so bile opravljene v programskem okolju PreonLab, v katerem so se s pomočjo testa s stožcem najprej ugotavljali parametri za tekoče blato, ki so bili kasneje uporabljeni pri simulacijah z avtomobilom. Uporabljen je bil Herschel-Bulkleyjev viskozni model, v katerem smo imeli štiri glavne parametre, katerih vpliv smo analizirali. Rezultati simulacij na avtomobilu so pokazali, da ima največji vpliv viskoznost blata, do neke mere velikost simulacijskega delca, zanemarljiv vpliv pa ima napetost tečenja. The aim of the bachelor thesis was to simulate mud soiling on car doors. The simulations were performed with the PreonLab software, in which the parameters for liquid mud were first established with the help of the cone test, and later used in the simulations on a vehicle. A Herschel-Bulkley viscosity model was used, in which the effects of 4 major parameters were analyzed. The results showed that the viscosity has the highest influence on the soiling, the size of the simulated particle to some extent, while the effect of yield stress can be neglected in vehicle simulations. blato test s stožcem Herschel-Bulkleyjev model viskoznost napetost tečenja mud slump cone test Herschel-Bulkley model viscosity yield stress true false false [F.
