| Abstract: | The 50m-diameter radio telescope antenna structure consists of a pedestal and a reflector. Through coupling the pedestal and the reflector together, this paper presents a FEM model, then the static and dynamic finite element analysis of the whole antenna structure was made under multiple loading conditions. The results show that the design scheme of the antenna structure meets the requirement of pointing accuracy and natural freuqency, and provides a theoretical basis for practical engineering. |
