Abstract

U završnom radu osmišljen je i konstruiran modul robotskog sustava Archer, tvrtke Inetec, koji služi za nerazorna ispitivanja stanja reaktorske kape u nuklearnoj elektrani. Modul se mora moći produljivati po potrebi, odnosno treba funkcionirati kao teleskopski mehanizam.
Zadatak je započet određivanjem ulaznih mjera, prostora u koji se modul ugrađuje i potrebnog produljenja modula. Pronađena su zatim patentna rješenja kako bi se odbio uvid u postojeće mehanizme. Uslijedila je izrada funkcijske dekompozicije gdje se pokazalo koje sve funkcije modul mora obuhvatiti te kako su one međusobno povezane. Za svaku funkciju dano je nekoliko konstrukcijskih rješenja u morfološkoj matrici. Odabirom različiti rješenja za svaku pojedinu funkciju, izrađena su različita konceptualna rješenja te je ocjenjivanjem prema traženim tehnološkim karakteristikama odabrano najbolje koje će ići u daljnju razradu.
Odabranom konceptu dane su gabaritne mjere kako bi obuhvatio glavnu funkciju teleskopskog pomicanja. Nakon detaljnije razrade, pronađeni su standardni dijelovi, a ostali dijelovi konstruirani su Inventoru-u. CAD modeli su spojeni u sklop te je prikazan spoj modula s Archer-om i reaktorskom kapom.

Abstract (english)

In this thesis, the module of Archer robotic system was designed. Archer, designed by INETEC company, is used for non-destructive inspections of nuclear reactor vessel head. Its module should be able to prolongate as needed, it should function as a telescopic mechanism.
Work has begun by determination of input measurement for installation space and of demanded prolongation. Then, patent solutions were found to gain ideas of existing mechanisms. Functional decomposition was made afterwards which showed all functions and their connections the module has to contain. Every function was given several design solutions put in a morphological table. Choosing different solutions for every function, various concepts were made. Every concept was graded depending on wanted technological characteristics and the best concept for further development was chosen.
The chosen concept was given overall dimensions for is demanded functions. After detailing, standard parts were chosen and other parts were made in CAD program Inventor. CAD models were joined in one assembly with both Archer and nuclear reactor vessel head.
