| Abstract: | Thermal analysis technique is the key technique in the design of space-borne antenna. A paraboloid antenna was taken for instance, with the study on the thermal balance relation in the astrospace, according to the thermal and flexible theories, using thermal analysis software and perpendicularity method to carry on simulation calculation. The main influence factors of square root error and temperature field for antenna were analyzed .The analysis result not only economizes a great deal of trial expenses but also raises reliability which have important instruction meaning. |
