U okviru ovog završnog rada prikazana je simulacija lijevanja kotača od aluminijeve legure AlSi13 u pješčani kalup. Shodno tomu definiran je uljevni sustav i provedena je simulacija u programu QuickCAST. Na temelju rezultata simulacije dodan je sustav napajanja s ciljem otklanjanja poroznosti unutar odljevka (kotača). U laboratoriju za Ljevarstvo u prostorima Fakulteta strojarstva i brodogradnje izliven je kotač sa iskustvenim uljevnim sustavom i sustavom napajanja. Nakon lijevanja odljevak je izmjeren i podvrgnut radiografskom ispitivanju. Prema izmjerama napravljen je CAD model i simulacija u programu. Rezultati radiografskog ispitivanja i simulacije su se većim dijelom poklapali osim manjih poroznosti u jednom dijelu vijenca kotača. Within this thesis, a casting simulation of aluminum alloy AlSi13 wheel in a sand mold is presented. Accordingly, the gating system was defined and a simulation was performed in the QuickCAST. Based on the simulation results, a feeding system was added with the aim of eliminating porosity inside the casting (wheel). A wheel with experiential gating system and feeding system was casted in the Foundry Laboratory at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb. After the casting process, the casting was measured and subjected to radiographic examination. According to the measurements, a CAD model and simulation in the QuickCAST were made. The results of the radiographic examination and simulation largely coincided except for minor porosities in one part of the wheel rim.

Diplomski rad predstavlja s tehničke strane sustav koji je jednostavan za izradu bilo kojoj vrsti korisnika zahvaljujući Arduino mikrokontroleru koji je svojim dizajnom i pristupačnošću dostupan i jednostavan za korištenje. Pri izradi je korišten Arduino Nano kao glavna komponenta inteligentnog autonomnog sustava za odlaganje otpada. Uvođenjem komponenata kao što su ultrazvučni senzor, solarna panela, akumulatorska baterija i senzor težine zajedno sve povezane preko Arduina omogućavaju izradu „pametne kante“. Zamišljena je da na pravedan način riješi problem plaćanja naknada za odlaganje otpada pojedinačnih korisnika. Komponente su izabrane kao najoptimalnija rješenja koja omogućavaju rad sustava. Softverski dio diplomskog rada napisan je u Arduino IDE programskom okruženju. Naredbama koje se šalju preko USB priključka Arduino mikrokontroleru omogućuju pravilan rad sustava. Zbog jednostavnosti pisanja i slanja koda prema Arudinu postoji mogućnost jednostavne nadogradnje i nadopune sustava u budućnosti. Prema osnovnim zamišljenim kriterijima izrade sustava koji objedinjuje područja kao što su elektronika, informatika, energetika i ekologija ostvaren je cilj prikaza njihovog udruživanja i mogućnost poboljšanja organizacije danas važnog pitanja o odlaganju otpada i načinu održavanja okoliša kako bi se osigurao što bolji sklad sa prirodom i okolišem., From the technical side, this thesis represents a system that is simple to create for any type of users thanks to the Arduino microcontroller, which with its design and accessibility makes it easy to use. In progress the Arduino Nano was used as the main component of the intelligent autonomous system for waste disposal. With the introduction of components such as ultrasonic sensor, solar panel, rechargeable battery and weight sensor together all connected via Arduino microcontroller enabled the creation of "smart trash can". It is intended to solve the problem of payment of individual waste disposal costs in a fair way. Components are selected as the most optimal solutions that enable system operation. The software part of the thesis is written in the Arduino IDE program environment. Commands that are sent via USB Arduino microcontroller allow proper operation of the system. Due to the simplicity of writing and sending the code to Arudino, there is the possibility of a simple upgrade and update of the system in the future. According to the fundamentally conceived criteria of system design that unites areas such as electronics, IT, energy and ecology, the goal of their association and the ability to improve the organization today as an important issue on waste disposal and environmental maintenance to ensure better harmony with nature and the environment.
