Abstract
U ovome radu prikazan je numerički proračun krutosti i optimiranje u kontekstu single failure proof konstruiranja ploče za precizni prihvat alata mosnog granika HROC predviđenog za ugradnju u nuklearnom postrojenju DONES. Proračun je započet izradom modela ploče za precizni prihvat diskretizirane trodimenzijskim i jednodimenzijskim konačnim elementima. Tako dobiveni modeli uspoređeni su na temelju rezultata numeričke analize metodom konačnih elemenata s postojećim preliminarnim proračunom ploče za precizni prihvat alata. Potom je model modificiran s ciljem zornijeg opisivanja ponašanja konstrukcije pri asimetrično narinutom opterećenju. Razmatrano je više različitih varijanti modeliranja spoja ploče za precizni prihvat alata s teretom, a pozornost je posvećena i modeliranju elastične veze vozička i ploče za precizni prihvat alata ostvarene pomoću čelične užadi. Nad usvojenim modelom provedeni su numerički proračuni za slučaj nominalne sheme opterećivanja konstrukcije i za slučaj otkazivanja jednog od twistlockova. Na koncu su izvršene modifikacije konfiguracije i geometrije ploče za precizni prihvat alata, kojima je osigurano ispunjenje kriterija krutosti i single failure proof konstrukcije. Predložene su dvije varijante izvedbe ploče za precizni prihvat alata za koje su navedeni kriteriji zadovoljeni.
Abstract (english)
The topic of this thesis is the numerical stiffness calculation and optimization of the suspended plate of the HROC, meant for installation in the DONES facility, in view of the single failure proof design requirements imposed on it. The calculation begins with the creation of both one- and three-dimensional discretized suspended plate models. These models were compared to the preliminary calculation of the suspended plate stiffness by evaluation of results obtained via numerical analysis using the finite element method. The obtained calculation models were further modified with the aim of achieving a more accurate representation of the behaviour of the suspended plate under asymmetric loading conditions. Multiple approaches regarding the interaction between the suspended plate and the weight that is to be lifted by it were considered. Additionally, the elastic joint between trolley and suspended plate achieved by means of steel ropes was evaluated. The calculation model obtained by this process was then used to perform numerical analyses of both symmetric loading conditions and loading conditions in case of a twistlock failure. Finally, the geometry and configuration of the suspended plate was modified to ensure that both stiffness and single failure proof criteria are met. Two variants were proposed which fulfilled the aforementioned criteria.
