摘　　要：多波束天线主面固定不动,副面及馈源安装在调整机构上。为保证副面的指向精度,应对调整机构的结构刚度进行评估。在不同工作姿态下对其结构进行力学计算,由计算结果可知,通过预调,副面调整机构的刚度能够满足要求。The main reflector of a multi-beam antenna is fixed,sub-reflector and feed are fixed in the adjusting mechanism.In order to meet the needs of directing accuracy,it is necessary to evaluate the stiffness of adjusting mechanism.Calculate the deformation of adjusting mechanism in different attitude,the results show that the stiffness of adjusting mechanism is sufficient by preset.

关 键 词：多波束天线 刚度分析 调整机构
