20.500.12556/DKUM-46410 Integracija hidravličnih dovodnih kanalov v ohišje univerzalnega prijemala Integration of hydraulic access channels into the housing of a universal grabbing device Univerzalno prijemalo 9.0 je proizvod podjetja KGL d.o.o. in je še v razvojni fazi z delujočimi prototipi. Notranje hidravlične povezave so izvedene z gibljivimi hidravličnimi cevmi, ki ne zadostujejo zahtevam zanesljivosti in varnosti zaradi notranjih gibajočih delov prijemala, kjer se zaradi zvijanja cevi v omejenem prostoru ter hidravličnih sunkov, v primeru višjih obremenitev lahko pojavlja neenakomeren pretok in tudi iztekanje hidravlične tekočine. Pojavila se je potreba po izboljšavi dovajanja hidravlične tekočine na način, ki bi odpravil težave oziroma povečal zanesljivost sistema. V magistrski nalogi je predstavljen obstoječi način delovanja, ki je analiziran za potrebe integracije, nato pa v skladu z geometrijskimi omejitvami izboljšan. Predlagana rešitev izvedbe je podprta z hidravličnim preračunom zmogljivosti in izgub sistema, ter trdnostno analizo nove geometrije. The universal grabbing device 9.0 is a product of KGL LLC and is still in development phase with working prototypes. Internal hydraulic connections are implemented by use of flexible hydraulic pipes, which are not sufficiently reliable and safe because of internal moving components, where due to pipe bending in a limited space and hydraulic pressure changes in high load situations can lead to uneven flow and leakage of hydraulic fluid. This arose the need for an improvement to the existing fluid delivery system, in a way that would eliminate current problems and enhance the reliability of the system. This work shows the current operating mode, which is analysed for the needs of integration and then in accordance to geometric constrictions improved. The proposed solution is backed up by means of hydraulic performance and losses calculations in the new system, as well as stress analysis of the modified geometry. univerzalno prijemalo hidravlika integracija trdnostna analiza Abaqus CAE universal grabbing device hydraulics integration stress analysis Abaqus CAE true true false [E.
