Abstract

U ovom radu prikazan je razvojni proces uređaja za ispitivanje zavara reaktorske posude i cijevi (eng. tangential weld), zavarenog spoja cijevi sa sigurnim dijelom primarnog cjevovoda (eng. nozzle to safe end weld), zavarenog spoja sigurnog dijela sa nastavkom cjevovoda (eng. safe end to pipe weld) te ulaza u cijev (eng. inner radius). Prvi korak razvojnog procesa opisanog u radu je istraživanje tržišta u sklopu kojeg su prikazani relevantni uređaju dostupni na tržištu kao i nekoliko patenata srodnih temi ovog rada. Nakon analize tržišta osmišljen je tehnički upitnik iz kojeg su proizašle definicija cilja te lista zahtjeva. Na temelju liste zahtjeva generirana je funkcijska dekompozicija razvijanog uređaja po kojoj je generirana morfološka matrica unutar koje su opisani neki od mogućih načina rješavanja parcijalnih problema definiranih funkcijskom dekompozicijom. Kombiniranjem parcijalnih rješenja u fazi koncipiranja generirana su dva koncepta te je definirana metoda evaluacije pomoću koje je odabran koncept pogodan za nastavak razvoja. U sklopu rada proveden je odabir pogonskih komponenti potkrijepljen pripadajućim proračunom. Potom su detaljnije opisani osmišljeni segmenti uređaja te su izneseni zaključci vezani uz nastavak razvojnog procesa.

Abstract (english)

The topic of this thesis is to present research and development process conducted on topic of development of a machine used for carrying out non-destructive examination of a reactor pressure vessel nozzle welds: tangential weld, nozzle to safe end weld, safe end to pipe weld and nozzle inner radius. In the first part of the paper data gathered during market research phase is presented. Afterwards main goal objective is set alongside with list of technical requirements by conducting a technical survey. The morphological matrix is generated based upon functional decomposition. Two concepts were created by combining partial solutions showed in morphological matrix. The method used to determine which concept is to be developed further is presented followed by carrying out the necessary calculations in order to select suitable power transmission components. Designed device is then presented with fully designed modules in focus. Thesis is concluded with presenting guidelines for future development of the given device.
