20.500.12556/RUL-135231 Analiza nosilnega elementa aktivnega dela transformatorja Analysis of the load-bearing element of the active part of the transformer Dvigovanje aktivnega dela transformatorja se izvede s pomočjo nosilnega elementa, ki je privarjen na pokrov. V nalogi sta sestavljena dva parametrična modela: volumski in lupinski model. Pri analizi rezultatov iz volumskega modela je bila uporabljena HSS-metoda, ki v lokalno povišanih koncentracijah napetosti poišče pravilnejšo rešitev. Pri lupinskem modelu so bili z lupinskimi elementi poenostavljeni tudi zvari. Iz primerjave je razvidno, da lupinski model v primerjavi z volumskim modelom ne prikaže enakega napetostnega stanja. S pomočjo volumskega modela je bil sestavljen katalog dimenzij različnih nosilnih elementov za dva različna materiala. Lifting of transformer's active part is performed with a load-bearing element welded to the cover. The thesis consists of two parametric models: a volume model and a shell model. For the volume model's results analysis, the HSS method was used, which finds more correct solution in locally elevated stress concentrations. In the shell model, welds were also simplified with shell elements. The comparison between models show that the shell model does not show the same stress compared to the volume model. With the help of a volume model, a catalogue of dimensions of different load-bearing elements was compiled for two different materials.
