Description

FAST radio telescope reflecting surface unit supports adjusting device

Technical field

The utility model relates to a kind of FAST radio telescope reflecting surface unit supports adjusting device, on the support bar that panel subunit is fixedly mounted on backrest upper strata by this supporting and adjusting device and joint ball, can the surface figure accuracy of accommodation reflex face unit by this supporting and adjusting device.

Background technology

FAST is the abbreviation of 500m bore spherical radio telescope (Five-hundred-meter ApertureSpherical radio Telescope), for specific national scientific development project, at present just in great Wo Dang depression, Jin Ke village, Ke Du town, Pingtang County, Bouyei-Miao Autonomous Prefecture of Qiannan, Guizhou Province is built.The natural Karst depression of this engineering utilization large nest water hole, as telescopical location, builds single port footpath the biggest in the world radio telescope.

FAST Active Reflector datum level is the sphere of a bore 500m, radius 300m, is made up of body support structure, actuator, reflecting surface unit.Active Reflector body support structure is made up of collar tie beam and lattice column and lattice column basis, main rope net, downhaul.Main rope net is geodesic triangular mesh.Reflecting surface cellular installation is online at main rope, and the length of side is about 10.4m ~ 12.4m, quantity about 4300.

FAST reflecting surface Unit Design, technology major requirement:
