摘　　要：Stewart并联机构作为大射电望远镜馈源系统的二次精调平台,由于馈源舱体的运动特性,精调平台的位置基准在测量坐标系下不断变化。针对大射电望远镜馈源系统精调平台位置基准的实时确定,给出了实用的测量方案及解算模型。在大射电望远镜馈源索支撑系统50 m缩比模型实验中得以应用。Stewart parallel manipulator used as fine tuning platform applying for the cable-suspend feed system of the large radio telescope. According to the platform＇ s movement of the feed system, the Stewart platform＇ s reference position was changing. The scheme for measuring and the mathematics model were presented in this paper that could satisfy the requirement for determining the reference position of the fine tuning Stewart platform in real time, which applied to the 50m-reduced-scale model of the feed system of the large radio telescope successfully.
