Thermal Analysis on Large Deployable Antenna

摘要

Large space deployable antenna attacts more and more attention in astronautics for its small volume in package state and meeting the demands of shpae and precision in deployed state. Because of adverse space circumstances, thermal analysis is essential for antenna design. According to the conduction-radiation principles and finite element analysis, temperature field, thermal deformation diagrams and thermal stress values of different points are presented when the antenna is at different places in its orbit. Some reasonable conclusions are obtained. These results will provide benefit reference for design and research on large deployable antenna.
