Utvärdering av mjukvara för utformning av kullager (Swedish)
Abstract [en]

This report has been written during my internship/master thesis at Thales Alenia Space, Cannes, FRANCE. The subject of the thesis is ball bearing design, and is focused on the software RBSDyn. This software has been developed by CNES, the French Center for Space Studies, and is used to simulate bearings behaviors under various conditions. My mission was to verify, test and implement this software for the company. In order to do so, the first step was to understand the bearing theory, which is the first part of this report. The second step was to use the software and verify its results, which is presented in the second section. Eventually, the final goal of this internship was to create a sequence to help Thales

Alenia Space engineers to design and select bearings, using this software and an Excel tool that needed to be created. Note that for confidentiality reasons, the values and names used for internal TAS mechanisms have been removed of this document.

Abstract [sv]

Denna rapport sammanfattar ett examensarbete som utfördes vid Thales Alenia Space, Cannes, Frankrike. Ämnet var utformning av kullager för utfällbara strukturer inom rymdindustrin och fokuserade på mjukvaran RBSDyn. Denna mjukvara har utvecklats av det franska rymdcentret CNES och används för att simulera kullagers beteende när de utsätts för olika laster. Uppdraget i examensarbetet var att verifiera, testa och implementera denna mjukvara för Thales Alenia Space. Det första steget i detta arbete var att gå igenom viktiga grundläggande samband inom kullagerteori. Det andra steget var att att verifiera resultaten från RBSDyn med de grundläggande sambanden. Det sista steget var att skapa en lämplig procedur för utformning av kullager; en procedur som ingenjörerna på Thales Alenia Space kan följa för att välja och utforma kullager för olika utfällbara strukturer. Proceduren innefattar mjukvarorna RBSDyn och Excel. Av sekretessskäl så har vissa värden och namn på utfällbara strukturer utelämnats i denna rapport.
