Abstract:Magistrsko delo se osredotoča na področje vibracijskih sit. V magistrskem delu smo se osredotočili na teorijo vibracijskih sit, analitični preračun vibracijskih sit, kalibracijo materialnega modela, DEM simulacijo in FEA simulacijo izbranega vibracijskega sita ter primerjava različnih izvedb vibracijskih sit. Poudarek v magistrskem delu je na numeričnem delu. V okviru raziskave je bilo analiziranih devet različnih izvedb vibracijskih sit, ki se med seboj razlikujejo po obliki in naklonu vibracijskega sita. Primerjava je bila izvedena tako, da smo vseh 9 različic simulirali v programskem orodju Ansys Rocky, kjer smo simulacijo izvedli z metodo diskretnih elementov (DEM). Med sabo smo primerjali sejalne sposobnosti vsake različice vibracijskega sita. Rezultate, pridobljene v programskem orodju Ansys Rocky, smo primerjali med seboj iz česar smo analizirali lastnosti vsake izvedbe vibracijskega sita. Za končno ovrednotenje mehanske ustreznosti konstrukcije vibracijskega sita je bila izvedena še analiza s pomočjo metode končnih elementov (FEA), s katero je bila preverjena statična trdnost konstrukcije izbranega vibracijskega sita.

Title:Comparison of different vibrating screen designs using numerical simulation based on discrete element method dem
Abstract:The master's thesis focuses on the field of vibrating screens. In the master's thesis, we focused on the theory of vibrating screens, analytical calculation of vibrating screens, calibration of the material model, DEM simulation and FEA simulation of the selected vibrating screen, and comparison of different designs of vibrating screens. The emphasis in the master's thesis is on the numerical part. Within the framework of the research, nine different designs of vibrating screens were analyzed, which differ from each other in the shape and inclination of the vibrating screen. The comparison was carried out by simulating all 9 versions in the Ansys Rocky software tool, where the simulation was carried out using the discrete element method (DEM). We compared the screening capabilities of each version of the vibrating screen. The results obtained in the Ansys Rocky software tool were compared with each other, from which we analyzed the properties of each design of the vibrating screen. For the final evaluation of the mechanical suitability of the vibrating screen design, an analysis was carried out using the finite element method (FEA), which was used to verify the static strength of the selected vibrating screen design.
