Description
Technical field
The present invention relates to the support and control field of Cabin in radio astronomical telescope, more particularly, to a kind of based on rope
Pose adjusts and control system.
Background technique
In radio astronomical telescope field, the small-signal from universe celestial body needs after primary reflection surface reflection focuses
To pass through subsequent processing, Cabin is one of pattern, and typical case case is U.S.'s ARECIBO telescope and China FAST
Telescope.In U.S.'s ARECIBO telescope, using 305 meters of fixed bore spherical reflective surfaces.On the massif of periphery, with three
Root rope supports a fixed triangle frame body panel by three towers, and being equipped in triangular framing platform lower can edge
The spherical canyon that moves in a certain range of guide rail, celestial body signal is after spheric reflection, through secondary in spherical canyon
It is focused with after triple reflection.For some determine direction, about 250 meters of the effective aperture of primary reflection surface.For Chinese FAST
Telescope, using 500 meters of bore spherical reflective surfaces of adjustable nodal section shape.On the massif of periphery, pass through six tower branch with six roots of sensation rope
A Cabin is propped up, primary position and attitude regulation are carried out to the Cabin by this six roots of sensation rope, six are utilized in Cabin
Linkage (Stewart platform) carries out further finer position and attitude regulation.For the direction that some is determined, entire ball
The a part in face forms about 300 meters of effective aperture of paraboloid.Celestial body signal is after the parabolic reflector, into Cabin
Reception system is handled.
Several hundred rice or above giant telescope, including radio telescope and optical telescope are reached for bore, are led
The Cabin of equipment such as radio telescope after reflecting surface and the minor face of optical telescope, generally apart from primary reflection surface distance compared with
Far, it is difficult to form the relatively-stationary tripodia as race glass or four-footed support construction between primary reflection surface, pass through
Rope and tower are supported and control is a kind of inevitable choice.
Being mainly characterized by for suspended-cable structure is non-linear, lag is big, inertia is big and rigidity is weaker.Such as the branch of FAST Cabin
Support and position control mode are no exception, Cabin be located at it is aerial apart from about 150 meters of reflecting surface, position and posture be easy by
To the influence of wind-force, the scheme of FAST be currently given by secondary fine tuning platform it is improved.The program is to secondary fine tuning platform
Performance requirement it is excessively high, when be applied to more large scale when may have larger difficulty, actual implementation and maintenance difficulties will increase
It is many, it is necessary to more accurate, the stable and easy to maintain rope supporting way of research and development.
