20.500.12556/DKUM-79990 Strukturna optimizacija telesa zobnika kuhinjskega robota diplomsko delo Structural optimization of the kitchen machine´s gear body Diplomsko delo obravnava strukturno optimizacijo telesa zobnika kuhinjskega robota. Na podlagi enačb iz priporočila VDI 2736 smo izračunali najmanjšo potrebno širino zobnika za zagotovitev napetosti v korenu zoba manjših od dopustnih. Nato smo s parametrično analizo po metodi končnih elementov ugotovili lokacijo in velikost potrebne obremenitve, ki povzroči enak odziv, kot da bi bila v kontaktu boka zob zobnika. Model zobnika smo pripravili v programskem paketu Siemens NX ter smo ga uvozili v programski paket za optimizacijo topologije, CAESS ProTOp. Po številnih poizkusih smo prišli do primerne strukture telesa zobnika z 38 % manj materiala kot pri polnem zobniku ob hkratni zagotovitvi, da so napetosti v korenu zoba manjše od dopustnih in da v notranjosti telesa zobnika ni koncentracij napetosti. The diploma thesis deals with the structural optimization of the kitchen machine’s gear body. Based on the equation from the guidelines VDI 2736, we have calculated the minimum required gear width to ensure that stress at the tooth root is smaller than the allowable. The location and the magnitude of the required load was determined by parametric analysis using the finite element method, which causes the same response as if the gear and the pinion were in contact. The gear model was prepared with the software package Siemens NX and was imported into the topology optimization software, CAESS ProTOp. After many attempts, we came to an adequate structure of the gear body with 38 % less material than a full solid gear body, while ensuring that the stress at the tooth root is smaller than the allowable and that in the interior of the gear body are no stress concentrations. optimizacija topologije analiza po metodi končnih elementov polimerni zobniki zmanjševanje mase napetost v korenu zoba CAESS ProTOp Siemens NX Ansys topology optimization finite element analysis polymer gears mass reduction tooth root stress CAESS ProTOp Siemens NX Ansys true true false [K.
