Abstract:V diplomskem delu je obravnavan transport pšenice v poševni in navpični smeri z uporabo Redlerjevega transporterja. Predstavljeno je teoretično ozadje delovanja Redlerjevega transporterja ter metoda diskretnih elementov (DEM), ki je bila uporabljena pri za izvedbo numeričnih simulacij. Izvedli smo analitičen preračun ter numerične simulacije v orodju Ansys Rocky. Izvedena je bila temeljita kalibracija materialnega modela za pšenico. Analizirali smo masne pretoke v treh regijah Redlerjevega transporterja in rezultate primerjali z analitičnim preračunom. Rezultati simulacije se ujemajo z analitičnim preračunom z manjšimi odstopanji. Analizirali smo ali v Redlerjevem transporterju material potuje z enako hitrostjo skozi celoten prerez transporterja, kar smo potrdili z analizo. Analizirali smo zapolnjenost korita, mesta največje obrabe Redlerjevega transporterja in sile na strgala. Končna izvedba Redlerjevega transporterja bi morala imeti spremenjena strgala kar bi izboljšalo praznjenje na koncu transportne poti.

Title:Desing and Numerical Analysis of Redler Conveyor Using Discrete Element Method (DEM)
Abstract:This thesis examines the transport of wheat in vertikal and inclined orientations using a Redler conveyor system. The teoretical background of Redler conveyor operation is outlined, together whit the Discrete Element Method (DEM), which was employed to perform numerical simulations. Both analytical calculations and numerical simulation were conducted in Ansys Rocky, accompaied by a comprehensive calibration of the material model for wheat. Mass flows were analyzed in three regions of the Redler conveyor and compered with analytical predictions, the results of the simulations show good agreement with analytical calculations with minor deviations. We analyzed wheather the material moves at a uniform velocity across the intire cross-section of the Redler conveyor, which was confirmed by data analysis. We examined In addition the degree of trough filling, location of maximum wear of Redler conveyor and forces acting on the scrapers . The study concludes that the final Redler conveyor desing should incorpurate modified scrapers in order to enhance material discharge at the end of the transport path.
