Descripció del contingut i pla d'activitats:
Objectives:
The objectives of this project will focus on the realization of
the camera support to be carried on board
the 3Cat-8 mission. We will go through all the phases, starting
with the design of the structure, which
will then be submitted to structural analysis software where it
will be validated after undergoing
resistance and vibration simulations. Finally, the model will be
3D printed.
Methodology:
In order to meet the objectives, the methodology to be followed
in this project will consist of two
parts.
Initially, a theoretical part, where all the fundamental aspects
of the 3Cat-8 mission will be covered.
Emphasis will also be placed on the specifications and dimensions
of both the camera and the support
that will be used, always strictly following the standardization
of the CubeSat. It will also provide the
theoretical structural foundations that will later serve as a
pillar when it comes to the design.
On the other hand, this project has a large practical component.
Firstly, using SOLIDWORKS design
software, the design of the structure will be carried out. This
consists of a top, front and bottom cover,
as well as multiple anchorages that will allow the CMS4 camera
and a magnetorquer to be anchored
to it on the same axis. Once the design is finalized and
assembled, the structural validation phase will
begin. In this section, using ANSYS software, we will validate
whether the design is optimal by
subjecting it to different load and vibration simulations. For
example, random vibration analysis or
quasi-static load analysis, among others. Finally, the structure
will go to the initial manufacturing
phase where a first 3D print will be made and then assembled.
Expected results:
Finally, the expected results of this project will focus on
developing the structure until the final
printing phase, with the aim that all the work carried out
throughout the project will contribute to the
progress of the 3-Cat8 mission and serve as documentation for
future missions
 
Overview (resum en anglès):
The aim of this final thesis is to carry out the CAD design and structural analysis of: the
support of the camera, the support for the rotor of the camera and a Magnetorquer, the
whole set on board the 3Cat8 mission, corresponding to one of the missions of the UPC
NanoSat Lab.
The 3Cat8 mission the following main objectives. Firstly, the educational component, a
project carried out by students, with the help of certain companies in the sector. Secondly,
the scientific component, focused on the observation of the ionosphere using GNSS-RO.
The elaboration of the design of the different components has been carried out through
the design software respecting the standard dimensions of the CubeSat, comprised in
a maximum available space and respecting the restrictions imposed by components of
the neighbouring units. Subsequently, the model has been simplified in order to be able
to replicate the structural behaviour of the components by optimising the computational
calculations for FEM simulations.
Once the model has been simplified, a series of analyses of modal type, random vibrations,
quasi-static creep and shocks in the FEM type environment have been carried out. Finally,
the results obtained, the are analyzed to get the conclusions.
The achieved results are considered successful. Finally, a series of recommendation are
made for the project¿s evolution.
