Abstract:  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.
Key words:  large radio telescope    source feed    integration of mechantronic and optic technologies    first feed-support system
