Abstract

FAST, five-hundred-meter aperture spherical radio telescope will be the largest radio telescope in the world which has been established science and research items recently. One of the innovative engineering concepts is the active main reflector which corrects spherical aberration on the ground to achieve full polarization and a wide band without involving a complex feed system. Besides the reflector simulation, it is very important to study the supporting structure for the reflecting surface. As the cable-net structure has been adopted, the in-depth study of back-structure is very important which is connected between cable-net and panel. In this paper, structure forms and parameters are studied in detail due to catch the costs and technical requirements. Throughout analysis, parameters are compared and modified. Meanwhile, Comparing experiments has carried out on some sample frames. The stiffness experiments with different load situations are going to confirm the feasibility of certain back-structure. Some conclusions is obtained, which can avail in further study.
