Embodiment Construction

[0015] The invention provides a large-scale radio telescope active reflection surface co-driving parallel mechanism array. As shown in Figure 1, the overall schematic diagram of the active reflector of the large radio telescope co-drives the parallel mechanism array. N parallel mechanism units (N: 1200-2000) are fixed on the base 7 according to the regular triangle distribution, forming the active reflector of the large radio telescope. Co-drive the parallel mechanism array. The regular hexagonal reflecting surface unit 1 of N parallel mechanism units is fitted to a rotating parabolic reflecting surface.

[0016] In FIG. 2 , the parallel mechanism unit includes three active branch chains and a regular hexagonal reflector unit 1 , and a support rod 3 in each active branch chain is connected to the reflector unit 1 through a spherical hinge 2 . The other two support rods 3 of the active branch chain are respectively connected to two adjacent reflection surface units 1 through s...

Abstract

The invention belongs to the components of a large radio telescope, especially relates to a co-driving parallel mechanism array on an active reflector of a large radio telescope with the number of the control nodes reduced and the control difficulty decreased. N parallel mechanical units are distributed and fixed on a base by the distribution of equilateral triangle, thus forming the co-driving parallel mechanism array on the active reflector of the large radio telescope. An active telescopic driver unit drives three adjacent reflector units at the same time, implementing the coupling amongst the reflector units. The regular hexagon reflector units of the N parallel mechanical units fit into the rotating parabolic reflector. The parallel mechanical array of the invention can reduce the number of the driving motor by 2/3, and decrease control difficulty; the engineering cost is reduced with one constraint branched chain reduced on each reflector. The rotating parabolic reflector can be fitted out via the parallel mechanism array, thus solidifying the need for large scale surface fitting.

Description

technical field [0001] The invention belongs to the scope of a co-drive mechanism for the active reflector of a large radio telescope, and in particular relates to a co-drive parallel mechanism for the active reflector of a large radio telescope that can reduce the number of drive motors, reduce the difficulty of control and engineering cost, and meet the requirements for large-scale curved surface fitting. array. Background technique [0002] Large-scale radio telescopes are the main research tools of radio astronomy, used to receive radio signals of various bands emitted by cosmic celestial bodies. Large radio telescopes also play an irreplaceable role in astronomy and even in the fields of earth environmental issues, solar physics and military affairs. With the needs of astronomy and the gradual maturity of radio technology, countries all over the world are competing to build radio telescopes with different performance, structure and scale. Currently the world's largest...
