摘　　要：介绍了中国天文学家提出的 FAST(five hundred m eter aperture spherical radio telescope)计划 ,对 FAST索支撑轻型指向跟踪系统的关键技术之一——一次支撑系统的机械结构进行了方案论证 ,从可靠性、响应速度等方面对自驱动和他驱动两种驱动类型进行了比较 .对自驱动方式的几种方案从运动性能和驱动性能等方面比较了各自的优缺点 ,最后得出了具有可行性的方案 .This paper introduces FAST (five hundred meter aperture spherical radio telescope) project presented by Chinese scientists. Furthermore, it gives a scheme discussion on mechanical structure of first feed\|support system, which is one of the key techniques of FAST. Two driving types, driving by itself and driving by others, are compared for their reliability, responsive velocity, etc. The advantages and shortcomings of several structural designs of driving by itsetf are analyzed in the aspects of motility and driving ability.
