摘　　要：由于受吊装条件限制及需根据不同的安装站址设计不同的支撑机构等原因，针对多波束天线的特点，本文提出了1种新结构，支撑机构采用基于Stwart的并联运动平台，天线反射体采用全碳纤维结构，利用有限元分析进行力学计算，结果表明所设计的天线性能很好的满足了天线指向精度要求。According to the characteristics of the multi-beam antenna, a new structure is proposed duce to the restraint of loading conditions and supporting mechanism caused by different installation site. The design of new structure is based on the Stwart parallel motion platform and the full-carbon fiber structure is adopted for the antenna reflector. The mechanical calculations by using finite element analysis indicates that the good performance can meet the requirements of antenna pointing accuracy.
