Bačar, Nik (author), Oman, Simon (mentor), Nagode, Marko (comentor)

V podjetju smo poskušali razviti robustno zemeljsko postajo z X/S frekvenčno pasovno anteno, namenjeno uporabi v obrambnih in vesoljskih komunikacijskih sistemih. Cilj naloge je razviti konstrukcijsko dovolj togo in vodotesno anteno, ki omogoča delovanje brez zaščitnega radoma ter zagotavlja zanesljivo delovanje pri hitrostih vetra do 100 km/h in preživetje sistema pri vetrovih do 200 km/h. V okviru naloge je bil izdelan poenostavljen model antene za numerične analize v programskem okolju Ansys. Na podlagi izvedenih simulacij so bile določene maksimalne obremenitve pogonskih sklopov ter zasnovan ustrezen pogonski sistem, ki zagotavlja zahtevano togost in zanesljivost delovanja.

• Title: Determination of the drive system for a satellite communication antenna

Abstract

The company aimed to develop a robust ground station equipped with an X/S-band antenna intended for use in defense and space communication systems. The objective of this thesis was to design a structurally rigid and waterproof antenna capable of operating without a protective radome while ensuring reliable operation at wind speeds up to 100 km/h and survival of the system at wind speeds up to 200 km/h. As part of the thesis, a simplified antenna model was developed for numerical analysis using the Ansys software environment. Based on the performed simulations, the maximum loads acting on the drive systems were determined, and a suitable drive system was designed to provide the required stiffness and operational reliability.
