| 摘 要： | Stewart平台作为馈源位姿精调机构安装在大型射电望远镜的悬挂馈源舱中 ,与悬索对馈源舱位姿的粗调机构一起 ,构成馈源位姿的两级调整系统。模拟了当Stewart平台对馈源位姿进行精调时 ,馈源舱由于Stewart平台反作用力的扰动而产生的位移响应。根据模拟分析结果和观测精度要求 ,提出了保证馈源位姿两级调整方案成功实施的改进设计

| Abstract: | A Stewart platform is assembled in the suspen ded feed cabin of the largest radio telescope as a fine tuning stable platform. In this way, the initial tuning to the position and orientation of the cabin wit h the cables and the fine tuning to the position and orientation of the feed wit h Stewart platform form a double-stage tuning system. The dynamic response of t he feed cabin to the disturbance from Stewart platform is simulated as Stewart p latform tunes the position and orientation of the feed. Based on the analysis an d the demand for observation precision, an improved design is proposed to ensure the success of the double-stage tuning. |
