U radu je napravljen proračun trakastog transportera potreban za njegovu kvalitetnu i pouzdanu konstrukciju koja će zadovoljavati zadanom režimu rada. Napravljena je automatizacija za upravljanje trakastog transportera uz pomoć Siemens PLC S7 1200 i Siemens HMI 1500 Comfort panela u Siemens TIA portalu. Cilj rada bila je izrada proračuna za konstrukciju i automatizaciju koja će zadovoljiti efikasnost, pouzdanost ali i troškove same izrade i implementacije. Pokazano je da se uz pomoć automatizacije koja je napravljena uz pomoć PLC-a kao glavnog elementa u tom lancu može podići efikasnost proizvodnje i sigurnost na radu koja bi uvijek trebala biti na prvom mjestu. Počevši od konstrukcije koja je napravljena na osnovu proračuna koji se temelji prije svega prema materijalu koji se transportira pa nadalje do željenog učinka, udaljenosti do koje želimo transportirati određeni materijal i svemu ostalome što je zaslužno da se ostvari zadana norma pod sigurnim uvjetima rada. Sama vizualizacija transportera napravljena je na način da operater ima u bilo koje vrijeme dostupan pregled ne samo transportera nego i statusa proizvodnje te ostalih uređaja u proizvodnji. Uloga trakastog transportera u rudarskoj industriji jako je bitna jer služi za prijevoz usitnjene rude na mjesto za sljedeći korak u proizvodnji ili lokaciju gdje se priprema za otpremu. Vrlo važna karakteristika kod trakastih transportera pogotovo u rudarskoj industriji je njihova pouzdanost. Transporteri u rudarskoj industriji često rade sa velikim kapacitetima i zahtjevima za čim više transportiranog materijala u jedinici vremena. Bitno je da transporter bude pouzdan i otporan na različita opterećenja koja se javljaju tijekom transporta kako ne bi došlo do oštećenja različitih dijelova i prestanka proizvodnje. In the paper, the calculation of the belt conveyor necessary for its high-quality and reliable construction, which will meet the given operating regime, was made. Automation was created for the control of the belt conveyor with the help of Siemens PLC S7 1200 and Siemens HMI 1500 Comfort panel in the Siemens TIA portal. The goal of the work was to create a budget for construction and automation that would satisfy efficiency, reliability, but also the costs of construction and implementation. It has been shown that with the help of automation, which was made with the help of PLC as the main element in that chain, production efficiency and safety at work, which should always be in the first place, can be increased. Starting from the construction, which is made on the basis of a calculation that is based primarily on the material being transported, and further to the desired effect, the distance to which we want to transport a certain material and everything else that is necessary to achieve the given norm under safe working conditions. The visualization of the conveyor itself is made in such a way that the operator has an overview of not only the conveyor but also the status of production and other devices in production available at any time. The role of the belt conveyor in the mining industry is very important because it serves to transport crushed ore to the place for the next step in production or the location where it is prepared for shipment. A very important characteristic of belt conveyors, especially in the mining industry, is their reliability. Transporters in the mining industry often work with large capacities and demands for as much transported material as possible in a unit of time. It is essential that the conveyor be reliable and resistant to the various loads that occur during transport, in order not to damage various parts and stop production.

Tema ovog završnog zadatka je konstrukcija uređaja za izradu cirkularnog polja provrta na kružnim šperpločama. Uređaj se temelji na konstrukciji jednostavne glodalice koja je namijenjena malim proizvodnim pogonima ili kućnim radionama. Za vrijeme razrade koncepata i konačnog rješenja, trebalo je voditi brigu o tome da uređaj mora biti siguran za korištenje od strane za to osposobljene osobe; te da nakon namještanja parametara i pozicije uređaj automatski vrši izradu provrta. Također, bitna stavka je točan izbor tehnologije za izradu polja provrta. Bitno svojstvo uređaja je prihvaćanje različitih alata poput prstastog glodala, čeonog glodala i svrdla, te mogućnost odabira nagiba alata kako bi se postigao željeni kut izrade provrta. Uz sve navedene zahtjeve bitan je i zahtjev cijene, koja mora biti što prihvatljivija kućnim radionama. Nakon koncipiranja uređaja pomoću funkcijske dekompozicije, morfološke matrice te konačne razrade odabranog koncepta, dolazi do proračuna u kojemu su proračunati bitniji konstrukcijski dijelovi. Na kraju razrade, pomoću programskog paketa SOLIDWORKS®, izrađuje se 3D CAD model s pripadajućom tehničkom dokumentacijom. The main theme of this task is to design a device for manufacturing a pollar array of holes on circular plywood. The device is inspired by the design of a simple mill that is targeted towards small workshops and home workshops. During the design of concepts and final solution, it was important that the device is safe to use by trained personnel, and that after setting the desired parameters and positioning the process is being automated. Also, important item was the correct choice of manufacturing technology for the array of holes. Another important property of the device is compatibility with various tools such as end mill, face mill and drill bits, and the asbility to adjust the tilt angle of the tool for desired hole angle. With all listed requests, it is very important to keep the device low cost, so it can be affordable to small home workshops. After the conceptualizing of the device by functional decomposition, morphological matrix, and final concept development, comes calculation of main components. At the end, the 3D CAD model is made by SOLIDWORKS® programme with associated technical documentation.

Izmjenjivači topline u zrakoplovima su glavni uređaji pomoću kojih zrakoplovi ostvaruju klimatizaciju. Postoje brojne vrste izmjenjivača topline, ali samo pojedini izmjenjivači topline mogu biti izrađeni na zadovoljavajući način i od odgovarajućih materijala koji se mogu ugraditi u zrakoplovnu konstrukciju. Glavni je zadatak klimatizacijskog sustava stvaranje ugodnog ozračaja za posadu i putnike, ali postoje određeni izazovi koji se javljaju u radu klimatizacijskog sustava. Najizazovniji dio za inženjere je proračun izmjenjivača topline u sustavu za klimatizaciju zrakoplova. Za proračun izmjenjivača topline koristimo karakteristične bezdimenzijske značajke. Pomoću proračuna utvrdit ćemo potrebu za toplinskim učinkom za odabrani tip zrakoplova. Osim toplinskog učina pomoću definiranih masenih protoka struja i njihovih karakterističnih stanja na ulazu može se proračunati potrebnu izmjenjivačku površinu lemljenog aluminijskog pločastog izmjenjivača topline. Heat exchangers in aircraft are the main means by which the aircraft achieves air conditioning. There are numerous types of heat exchangers, but only some heat exchangers can be made satisfactorily and from suitable materials that can be implemented in the aircraft construction. The main task of the air conditioning system is to create pleasant atmosphere for the crew and passengers, but there are certain problems that occur in the operation of the air conditioning system. The most challenging part for engineers is the calculation of the heat exchanger in the air conditioning system of the aircraft. For the calculation of the heat exchanger, we use characteristic dimensionless features. Using the calculation, we will determine the need for thermal power for the selected type of aircraft. In addition to the thermal effect, the required exchange surface of the brazed aluminium plate heat exchanger can be calculated using the defined mass current flows and their characteristic states at the entrance.

Zadani zadatak je konstruiranje trostupanjskog reduktora sa kosim zubima sa koaksijalnim izlaznim vratilima. Materijal za izradu zupčanika je Č5420, za izradu vratila Č4171, a materijal za izradu kućišta je NL700. Proračun je izrađen po stupnjevima. Treći stupanj sa manjim prijenosnim omjerom je predimenzioniran, no to je neizbježno. Pogonsko vratilo je istog materijala kao zupčanik i izrađuju se zajedno. Gonjeno vratilo i zupčanik su spojeni sa dva pera razmaknuta za 120˚. Obrada zupčanika i vratila je kovanje, a daljnja obrada po potrebi je tokarenje, glodanje, brušenje i bušenje. Za podmazivanje i hlađenje zupčanika koriste se brizgaljke u obliku bakrenih cijevi, koje brizgaju ulje na zahvat zupčanika., The default task was to construct a three-stage reducer with helical teeth with coaxial output shafts. The material for the manufacture of gears is Č5420, for the manufacture of shafts Č4171, and the material for the manufacture of the case is NL700. The budget is made by degrees. The third stage with a smaller gear ratio is oversized, but this is inevitable. The drive shaft is the same material as the gear and is made together. The chased shaft and gear are connected to two keyways spaced by 120°. The processing of the gears and shafts is forging, and further processing if necessary is turning, milling, grinding and drilling. For lubrication and cooling of the gears, injectors in the form of copper pipes are used, which inject the oil to the gear grip.

Zadatak ovog završnog rada je izvršiti proračun jednogredne mosne dizalice. U prvom dijelu bit će ukratko opisane mosne dizalice i njihova primjena. Sljedeći dio zadatka prikazuje određivanje opterećenja mosnog nosača dizalice, gdje je pri konstruiranju odabran standardan toplo valjani profil koji zadovoljava zadane uvjete čvrstoće i krutosti. Zatim je prikazan proračun čeonih nosača izrađenih iz standardnih toplo valjanih limova. Kod čeonih nosača napravljen je i proračun zavarenih spojeva, vijčanog spoja s mosnim nosačem, te osovine kotača čeonih nosača. Dalje je u zadatku potrebno napraviti izbor uzdužnih i vertikalnih nosača, tako da oni zadovoljavaju zadane uvjete čvrstoće i krutosti. Zbog stabilnosti vertikalnih nosača postavljen je oslonac na sredini od ukupne duljine nosača, da bi smanjili duljinu izvijanja, a samim time i povećali njihovu nosivost. Pri izboru kuke korišten je „DIN 15 404-1“ standard, gdje je bitno odabrati kuku tako da ona zadovoljava zadane uvjete sigurnosti i čvrstoće. Kod izbora užeta korišten je „EN 12385“ standard. Elektromotor je odabran na temelju snage potrebne za jednoliko podizanje, spuštanje tereta. Na kraju je izvršena „FEM“ analiza mosnog nosača s koje se može vidjeti da je nosač pravilno konstruiran., The task of this thesis is to execute the calculation of an overhead single-girder bridge crane. In the first part, there will be a short description of overhead bridge cranes and their uses. The next part of the task is to determine the loads of the bridge beam made out of hot rolled steel, that satisfy the given strength and deformation limits. Next it is shown the calculation of the trucks made by welding standard hot rolled sheets. For the trucks, the calculation of the welds, screw connection with the bridge beam and the shaft of the wheels is shown. Next, the calculation of the longitudinal and vertical beams is made so that they satisfy the given strength and deformation limits. For the stability of the vertical beam, there is a support at the half of the beam length, so that the deflection is lowered and, at the same time, the capacity of the beam is increased. The crane hook was selected using the „DIN 15 404-1" standard, where it is important that the hook satisfies given safety and strength limits. The rope was selected using the „EN 12385“ standard. The electric motor is selected based on the power needed for uniform lifting and lowering of the load. In the end, the „FEM" analysis of the bridge beam is made, where it is shown that the beam is properly constructed.

Tema ovog završnog rada je proračun nosive konstrukcije proizvodne hale. Prije nego je pristupljeno samom proračunu, opisane su vrste i primjene nosača s posebnim naglaskom na glavni element ove konstrukcije – rešetkasti nosač. Nakon teorijskog dijela rada, slijedi određivanje glavnih opterećenja na prethodno modeliranu proizvodnu halu uz korištenje softverskog paketa SolidWorks iz kojeg su izvučene sve potrebne sile i momenti za proračun. Zadnji dio rada je proračun odabranih elemenata nosive konstrukcije prema Eurocodu te analiza rezultata., The topic of this bachelor thesis is calculation of the supporting structure of the production hall. Before the calculation itself is approached, the types and applications of beams are described with a special emphasis on the main element of this structure - the truss. Following the theoretical part of the work, the main loads on the previously modelled production hall are determined using the SolidWorks software package, from which all the resulting displacements and stresses are obtained. The final part of the thesis is dedicated to the calculation of the previously selected elements of the truss. An analysis of the results is also included.

Tema rada je projektiranje, izrada i kontrola nosive grede koja služi za transport kotlovskih komponenti ukupne mase 60 tona. Zbog rasporeda opterećenja sredina nosive grede je opterećena s 30 tona, dok je svaki kraj opterećen s 15 tona. U radu je projektirana i proračunata greda tako da joj najveće naprezanje prouzrokovano težinom transportnih cjelina ne prelazi dopušteno naprezanje, koje je manje od granice tečenja materijala za vrijednost faktor sigurnosti. Projektiranje nosive grede je obavljeno u programu „Autodesk Inventor 2021“, gdje se nakon unošenja potrebnih podataka o materijalu, opterećenjima i osloncima reprezenta dobio proračun istog. Najveće naprezanje dobiveno proračunom u navedenom programu iznosi 197,9 MPa, najveći progib grede je 0,9442 mm i faktor sigurnosti za iznos naprezanja 1,9. U idućem dijelu rada je obavljen ručni proračun zavarenih spojeva konstrukcije. Uspoređivanjem reduciranog naprezanja za svaki zavareni spoj i dopuštenog naprezanja u zavarima dokazano je da svi zavari zadovoljavaju postavljene uvjete. U trećem dijelu rada su objašnjeni tehnološki postupci izrade i kontrole nosive grede. Pozicije koje se zavaruju na HEB 240 profil se režu vodenim mlazom iz limenih ploča odgovarajućih debljina na određene dimenzije. Zavarivanje istih se provodi REL postupkom zavarivanja uz korištenje bazične elektrode EVB 50, koja ima visoku granicu tečenja do 610 MPa. Vizualna kontrola je potrebna prije, za vrijeme i nakon postupka zavarivanja nosača, a ultrazvučnom metodom je potrebno nakon zavarivanja utvrditi postoje li greške, pukotine ili druge nepravilnosti u šavu., The topic of the paper is the design, manufacture and control of a load-bearing beam used for the transport of boiler components with a total weight of 60 tons. Due to the load distribution, the middle of the load-bearing beam is loaded with 30 tons, while each end is loaded with 15 tons. The paper also designed and calculated the beam so that its maximum stress caused by the weight of the transport units does not exceed the allowable stress, which is less than the yield strength of the material for the value of the safety factor. The design of the load-bearing beam was performed in the program "Autodesk Inventor 2021", where after entering the necessary data on the material, loads and supports of the representative, the calculation of the same was obtained. The maximum stress obtained by the calculation in the mentioned program is 197.9 MPa, the maximum deflection of the beam is 0.9442 mm and the safety factor for the amount of stress is 1.9. In the next part of the work, a manual calculation of welded joints of the structure was performed. By comparing the reduced stress for each welded joint and the allowable stress in the welds, it was proven that all welds meet the set conditions. The third part of the paper explains the technological procedures for the manufacture and inspection of load-bearing beam. The positions that are welded to the HEB 240 profile are cut with a water jet from sheet metal of appropriate thickness to certain dimensions. They are welded by MMA welding using the basic electrode EVB 50, which has a high yield strength of up to 610 MPa. Visual inspection is required before, during and after the welding procedure, and an ultrasonic method is required to determine defects, cracks or other irregularities in welds.

Povećanje energetske učinkovitosti elektroenergetskog sektora je opredjeljenje svih nacionalnih prijenosnih operatera. Jedan od temeljnih ciljeva je smanjenje gubitka u elektroenergetskim mrežama. Električne mreže su jedan od najvažnijih dijelova elektroenergetskog sustava. Pouzdanost isporuke te kvaliteta električne energije neposredno ovisi o vrsti i izgrađenosti elektroenergetske mreže. Poznato je da se gubici u prijenosnoj mreži mogu definirati kao razlike preuzete i predane električne energije. Određivanje gubitaka na vodovima ima nekoliko temeljnih zadaća. Prva zadaća jeste odrediti razliku između izračunatih gubitaka i stvarnih gubitaka te odrediti razlog za tu razliku i da pokaže neophodne smjernice za poduzimanje mjera za smanjenje gubitaka. Drugi zadaća je procjena indeksa gubitaka za planiranje i formulaciju različitih planova. U ovom rada je prikazan novi pristup za smanjenje pogreške između izračunatih i stvarnih gubitaka korištenjem nove metode koja se bazira na tri modificirana moda, odnosno sasvim novim pristupom za izračun indeksa gubitaka. U ovom doktorskom radu predložena metoda znatno smanjuje pogrešku u odnosu na klasičnu metodu na tri moda. Također, razvijen je algoritam koji opisuje korake za implementaciju metode. Increasing the energy efficiency of the electricity sector is the commitment of all national transmission operators. One of the main goals is to reduce losses in electrical networks. Electrical networks are one of the most important parts of the electric grid. Delivery reliability and the quality of electricity directly depend on the electrical networks. It is well known that losses in the transmission network can be defined as the difference between the electricity taken and delivered. Determining the losses in overhead power lines has several basic tasks. One task is to determine the difference between calculated losses and actual losses, to determine the reason for the difference between calculated and actual losses, and to present the necessary data for taking measures to reduce losses. The second task is an estimation of the loss index for planning and formulation of various plans. The purpose of this paper is to present a new approach to reduce the difference between calculated and actual losses by modifying the method in three modes, or a new approach to calculating the loss index. The proposed method in this doctoral thesis significantly reduces the error in relation to the classic three-mode method. Also, an algorithm has been developed that describes the steps for implementing the method.

Na temelju internih i knjigovodstvenih podataka izrađene su tehnološke karte i analitičke kalkulacije proizvodnje. Rezultati su prikazani vrijednostima apsolutnih i relativnih pokazatelja uspjeha. Na temelju pokazatelja utvrđena je ekonomska opravdanost i rentabilnosti svih analiziranih kultura. Najisplativija kultura za proizvodnju je uljana repica što potvrđuje ostvaren financijski rezultat od 6.697,39 kn/ha i cijena proizvodnje 1,81 kn/kg. Prema strukturi troškova najzastupljenija su mineralna gnojiva i sredstva za zaštitu bilja. Prema relativnim pokazateljima proizvodnost rada kod pšenice iznosi 1,4 t/h, kod ječma 1,1 t/h te kod uljane repice 0,45 t/h. Koeficijent ekonomičnosti za ječam i uljanu repicu iznosi 2,1, dok za pšenicu 1,9. Najviša razina rentabilnosti postignuta je kod uljane repice (RP= 52,75 %), srednja razina kod proizvodnje ječma (RP=52,33%), dok je najniža kod proizvodnje pšenice (RP = 46,45%)., The aim of this paper is to describe organization and technology of production of field crops (oilseed radish, wheat and barley) on the Dragan Čolaković family farm during the production years 2018/2019. The farm is focused exclusively on crop production and currently cultivates 251, 75 ha of arable lands. Data was processed using the analysis, synthesis, comparison, calculation and SWOT analysis methods. Based on the internal and bookkeeping data, technological maps and analytical calculations of production were made. The results are presented with values of absolute and relative indicators of success. Based on the indicators, the economic justification and rentability of all analysed crops were determined. The most profitable crop for production is oilseed radish, which was confirmed by the achieved financial result of HRK 6,697.39 / ha and the production price of HRK 1.81 / kg. Based on cost structure, the most common are mineral fertilizers and plant protection products. Based on relative labour productivity indicators, it is 1.4 t / h for wheat, 1.1 t / h for barley and 0.45 t / h for oilseed radish. Economic coefficient for barley and oilseed radish is 2.1, while for wheat it is 1.9. The highest level of rentability was achieved in oilseed radish (RP = 52.75%), average level in barley production (RP = 52.33%), while the lowest was in wheat production (RP = 46.45%).

Završni rad na temu razrade koncepta i konstrukcijskog rješenja dvosmjernog horizontalnog konvejera koji pijeskom puni bunkere postavljene u niz, izrađen je u skladu sa proračunom i na temelju kombinacije postojećih rješenja konvejera za slične zahtjeve i pripadajuće literature. Uvodni dio sastoji se od općenitog razmatranja o prenosilima s pogonskim trakama, analize principa rada nekih postojećih proizvoda, te vrednovanja i odabira najboljeg koncepta. Na temelju tog koncepta zadatak ide u daljnju razradu, uz zadane ulazne parametre: ukupna dužina trake, visina vozne trake i volumenski protok. Radu je uz proračun priložena tehnička dokumentacija u obliku sklopnog crteža konvejera sa svim bitnim presjecima i detaljima. The subject of this final paper: developing the concepts and designing the two-way horizontal conveyor which fills the bunkers arranged in a row with the sand, has been made in line with the calculations and the combination of existing conveyor solutions information and required literature. The introduction contains general descriptions of conveyors, analyses of some of the existing products, the evaluation of the concepts and choosing the best one. The chosen concept then undergoes further development and elaboration, together with the assigned entrant parameters: the belt lenght, the height of the belt placement and volumetric flow rate. The technical documentation of the conveyor is attached at the end of the paper.
