MODELLAZIONE SEMPLIFICATA DELLA SCHEDA MADRE OPEN-SOURCE PYCUBED COMPLETA DI COMPONENTI

CubeSat nano-satellites are, to date, the cheapest independent means of bringing a payload into orbit. While the reference standards for this satellite are widely defined to facilitate access to space, the CubeSat must respond to a rigorous experimental test campaign. The most frequent cause of unsuccessful launches is due to the breakage of the electronic boards or the connections of the soldered electronic elements due to excessive vibrations or high stresses due to the shock test. For this reason, the phases of numerical design with finite elements and experimental verification of Printed Circuits (PCBs) with components soldered on are extremely delicate moments and of fundamental importance for evaluating the integrity of the cards during launch. The simulation of the mechanical behaviour of PCBs depends mainly on the properties of the material, the geometry and the type of components mounted on it. For this reason, the purpose of this document will not be solely to provide a mechanical characterization of PyCuded open-source printed circuits; but above all that of generating a reliable simplified numerical model of the PCB that reflects the dynamic behaviour of the motherboard complete with the components required for launch. To support and for completeness of the analysis, numerical/experimental modal comparisons will be used that will allow us to validate the proposed models. In this way, all the designers who will use these open-source PCBs, will be able to simulate, in the most real way possible, the complete mechanical behaviour of the printed circuit in the presence of components, reducing time, costs and design risks
