Thermal Analysis on Small Satellite Structure Under Cosmic Radiation Effect

The thermal effect is one of the most concerning and studying the case of heat transfer and thermal deformation in the aerospace structure in general and the structure of artificial satellites in particular is fundamental for a space exploration mission. Heat can appear when satellites are affected by solar radiation and radiation from planets. For spatial structures, the theory of heat transfer has been applied quite effectively. In this study, we applied Finite Element Method for analyzing temperature distribution and thermal deformation by using commerce software. The results showed that the analysis on thermal effect of a selected satellite model with the temperature difference of two opposite sides on the structure of the satellite. Specifically, the temperature distribution and thermal deformation are presented for the three materials. Finally, we evaluate the effectiveness of materials applied to satellite structures.
