Abstract

Razvoj i lansiranje malih satelita poput CroCubea predstavljaju značajan napredak u svemirskoj tehnologiji i istraživanju. Minijaturizacija i tehnološki napredak omogućuju smanjenje troškova i povećanje funkcionalnosti svemirskih misija. Ovaj rad obuhvaća sve ključne faze od dizajna do lansiranja, uključujući analizu komponenti, sustava i vibracijskih ispitivanja.
CroCube je optimiran za ručno sklapanje korištenjem metode DFA, što je rezultiralo smanjenjem broja dijelova s 81 na 61 te povećanjem efikasnosti montaže s 23,47 % na 44,13 %. To je smanjilo troškove nabavke i izradbe te vrijeme montaže s 472,89 na 414,65 sekundi.
Vibracijska ispitivanja i simulacije dokazale su strukturnu stabilnost konstrukcije. Iako su simulacije ograničene točnosti i pouzdanosti, koriste se jer su izrazito korisne prilikom procesa konstruiranja. Unatoč tome, stvarna ispitivanja su nužna kao dokaz da će satelit izdržati ekstremne uvjete tijekom lansiranja i rada u orbiti, omogućujući mu uspješno izvršavanje predviđene misije.
Ovaj sveobuhvatni pristup izradi CroCubea može poslužiti kao model za buduće projekte malih satelita, doprinoseći daljnjem razvoju i inovacijama u svemirskoj industriji. Rad pruža uvide i praktične primjene korisne za istraživače i inženjere u budućim misijama istraživanja svemira.

Abstract (english)

The development and launch of small satellites like CroCube represent significant advancements in space technology and research. Miniaturization and technological progress enable cost reduction and increased functionality of space missions. This work encompasses all key phases from design to launch, including component analysis, system evaluations, and vibration testing.
CroCube is optimized for manual assembly using the DFA method, resulting in a reduction of parts from 81 to 61 and an increase in assembly efficiency from 23.47% to 44.13%. This has lowered procurement and production costs and reduced assembly time from 472.89 to 414.65 seconds.
Vibration tests and simulations have proven the structural stability of the construction. Although simulations are of limited accuracy and reliability, they are extremely useful during the design process. Nevertheless, actual tests are necessary to ensure that the satellite will withstand the extreme conditions during launch and operation in orbit, allowing it to successfully complete its intended mission.
This comprehensive approach to the development of CroCube can serve as a model for future small satellite projects, contributing to further development and innovation in the space industry. The work provides insights and practical applications useful for researchers and engineers in future space exploration missions.
