Abstract

U ovom završnom radu osmišljena su i konstrukcijski detaljno razrađena ručno pogonjena kolica specijalizirana za transport i punjenje baterije korištene u bolidu Formula Student natjecanja. Glavni cilj bio je razviti mobilno i funkcionalno rješenje koje će omogućiti sigurno i jednostavno prenošenje baterije unutar boksa (engl. pit area), uz integraciju sustava za punjenje kako bi se smanjila potreba za dodatnom opremom tijekom natjecanja.
Rad započinje analizom postojećih rješenja i pregledom tehničkih zahtjeva propisanih pravilima Formula Student natjecanja, s posebnim naglaskom na sigurnost pri radu s visokim naponom i ergonomiju pri rukovanju teškim komponentama. Nakon definiranja tehničkih i funkcionalnih zahtjeva, razvijeno je nekoliko konceptualnih rješenja kolica, koja su vrednovana prema unaprijed definiranim kriterijima kao što su stabilnost, jednostavnost korištenja, sigurnost i integracija sustava za punjenje.
Na temelju rezultata analize, odabran je koncept koji je dobio najviše ocjene te je napravljena detaljna konstrukcijska razrada. U sklopu razrade izrađeni su detaljni proračuni ključnih elemenata, uključujući nosive komponente i mehanizam za zaključavanje baterije tijekom transporta. Također, izrađena je kompletna tehnička dokumentacija i 3D model pomoću CAD softvera, čime je omogućena vizualizacija konačnog dizajna te provjera njegove izvedivosti i praktičnosti.
Osim konstrukcijskih aspekata, rad uključuje i pregled sigurnosnih mjera koje je potrebno provesti kako bi kolica bila usklađena s međunarodnim standardima za rad s litij-ionskim baterijama, uključujući izolaciju električnih spojeva i zaštitu od mehaničkih oštećenja. Kroz integraciju rješenja za punjenje unutar kolica, omogućena je dodatna funkcionalnost koja olakšava rad tehničkog tima i smanjuje vrijeme potrebno za pripremu vozila tijekom natjecanja.
Kao rezultat ovog rada, razvijeno je inovativno i praktično rješenje koje zadovoljava sve postavljene tehničke zahtjeve i pridonosi poboljšanju operativne učinkovitosti tijekom natjecanja Formula Student.

Abstract (english)

In this thesis, manually powered carts designed specifically for transporting and charging the battery used in a Formula Student race car were thoroughly conceptualized and structurally developed. The primary objective was to create a mobile and functional solution that would enable the safe and simple transport of the battery within the pit area, integrating a charging system to minimize the need for additional equipment during competitions.
The thesis begins with an analysis of existing solutions and a review of the technical requirements outlined by the Formula Student competition rules, emphasizing safety when working with high voltage and ergonomics for handling heavy components. After defining technical and functional requirements, several conceptual designs for the cart were developed and evaluated according to predefined criteria, such as stability, ease of use, safety, and charging system integration.
Based on the evaluation results, the highest-rated concept was selected for detailed structural development. This phase included precise technical calculations of key components, such as load-bearing structures and a locking mechanism for securing the battery during transport. Additionally, comprehensive technical documentation and a 3D model were created using CAD software, allowing for visualization of the final design and verification of its feasibility and practicality.
In addition to structural aspects, the thesis also addresses safety measures necessary for compliance with international standards for handling lithium-ion batteries, including electrical connection insulation and protection against mechanical damage. By integrating a charging system within the cart, additional functionality was achieved, simplifying the technical team’s work and reducing the time required for vehicle preparation during competitions.
As a result of this thesis, an innovative and practical solution was developed that meets all specified technical requirements, contributing to improved operational efficiency in Formula Student competitions.
