| Abstract: | The structure design of a large truss antenna pedestal for satellite communication was discussed,involving optimization of the structure form of main components, precision of key components, mechanics calculation, axial accuracy, and emulation analysis of FEA to the antenna structure model.The result was confirmed by practice.The results show that performance of the optimized antenna＇ s structure components would meet designed requirements. This design presents a technical reference model, which could be of great significance to other large-trussed antenna structure design. |
