This paper presents strength and thermal studies, as well as an analysis of the design material for the development of a nanosatellite model. By using the SolidWorks software environment, an effective solid-state finite-element model of a nanosatellite are developed, on the basis of which the stress-strain state of the nanosatellite is analyzed, as well as the criteria for evaluating the strength of nanosatellite structural elements made of composite materials. The strength reserves are determined, the maximum displacements of the structural elements are found. It is determined that the developed model of the nanosatellite meets the conditions of strength and thermal conditions. [For the full proceedings, see ED623149.]
