| Abstract: | The reflector antenna structure is the physical carrier and guarantee for the realization of electrical properties. The mechanical structure design of a reflector antenna on satellite is discussed, the structure types and structure design of carbon fiber composite materials reflector and back frame are emphasized. The finite element modeling is established. The modal analysis, sine vibration analysis, and thermal deformation analysis of the finite element model are accomplished. It is shown that the antenna has sufficient rigidity and strength to satisfy the design demand based on simulation analysis and vibration test. The presented study provides useful guidance of other satellite reflector antenna designers. |
