Abstract:Magistrsko delo se osredotoča na področje mostnih žerjavov in grabilcev za razsuti tovor. V magistrskem delu smo podrobno opisali konstrukcijo mostnih žerjavov in izvedli preračun ključnih elementov mostnega žerjava v skladu z evropskim standardom SIST EN 13001, ki določa smernice in potrebne parametre za zasnovo mostnih žerjavov. Poleg tega smo zasnovali in analizirali grabilec za sipke snovi, vključno z analitičnim preračunom kinematike grabilca ter sil, ki delujejo na grabilec med delovanjem. Poudarek magistrskega dela je na numeričnem delu. Po modeliranju grabilca v SolidWorks-u smo prenesli geometrijo v programski paket Ansys Rocky, kjer smo uporabili parametre iz analitičnega preračuna, določili robne pogoje in izvedli simulacijo z metodo diskretnih elementov (DEM). V sklopljenem modelu smo rezultate, pridobljene z uporabo metode DEM, prenesli v PrePoMax, kjer smo izvedli trdnostno analizo geometrije grabilca z metodo končnih elementov (FEM). Celoten numerični postopek smo izvedli dvakrat, da bi optimizirali in dimenzionirali grabilec ter podaljšali njegovo življenjsko dobo zaradi obrabe ob stiku z razsutim tovorom, v našem primeru s premogom. Na koncu magistrskega dela smo predstavili numerične rezultate in prikazali, kako numerične metode prispevajo k naprednemu in optimalnem procesu konstruiranja mehanskih izdelkov.

Title:Designing a bridge crane using the sist en 13001 standard and integration of analytical and advanced simulation methods
Abstract:The master's thesis focuses on the field of bridge cranes and grabbers for bulk materials. The work provides a detailed description of the structural design of bridge cranes and includes calculations of key crane components in accordance with the European standard SIST EN 13001, which defines the guidelines and required parameters for crane design. Additionally, we designed and analyzed a bulk material grabber, including an analytical calculation of the grabber’s kinematics and the forces acting on it during operation. The emphasis of the thesis lies in the numerical analysis. After modeling the grabber in SolidWorks, we transferred the geometry to Ansys Rocky, where we applied parameters from the analytical calculations, defined boundary conditions, and performed a Discrete Element Method (DEM) simulation. Using a coupled model, we transferred the DEM results to PrePoMax, where we conducted a structural analysis of the grabber’s geometry using the Finite Element Method (FEM). The entire numerical procedure was performed twice to optimize and dimension the grabber, as well as to extend its service life by reducing wear caused by contact with bulk material—in this case, coal. Finally, the thesis presents the numerical results and demonstrates how advanced numerical methods contribute to an optimized and modern mechanical design process.
Keywords:bridge cranes, standard SIST EN 13001, bridge crane calculation, clamshell grab bucket calculation, finite element method, discrete element method.
