Abstract
The thermal uniformity of large mesh antennas in orbit is influenced by the thermal encironment, which results in thermal deformation and affects the performance of the antenna.Therefore, it is the basis of improving antenna performance to accuratey predict the temperature and analyze the influence facors of the thermal stability of the antenna.In this paper, a large mesh antenna model is constructed by using the FEM analysis software to simulate the thermal response of the flexible connecting structure of the metal mesh reflector, tension cable and rib component.The analysis results show that the temperature of antenna metal mesh and rib components are sensitive to the connection of the two, and their connection to tension rope is not sensitive. The tension cable is sensitive to the connection of the metal mesh and is insensitive to the connection of the rib components. The above analysis can provide an important reference for the design of large mesh antenna connection structure.
