Embodiment Construction

[0033] The present invention proposes an assembleable reflector module unit 1 with an independent unfolding function. The module unit 1 is composed of a hexagonal expandable truss 2, a reflection rope net 3, and a rope connection device 4, such as figure 1 shown. The implementation process of each part is introduced in detail below.

[0034] 1. Hexagonal Deployable Truss 2

[0035] The structure of the hexagonal expandable truss 2 is as follows:

[0036] The hexagonal expandable truss 2 is made up of plane triangle 5, and plane triangle 5 is made up of synchronous folding rod 6 and two middle oblique rods 7 again, and synchronous folding rod 6 is made of synchronous power hinge 9 with synchronous rod 8 equal in length (also Said synchronous hinge 9) is connected, and this synchronous folding bar 6 can realize the synchronous unfolding function of synchronous bar 8; Plane triangle 5 constitutes as figure 2 As shown, its unfolding and retracting movement process is as follow...

Abstract

The invention discloses a large spatial assembly type antenna reflector modular unit and an assembly method thereof. The modular unit comprises a hexagonal extensible truss, a reflecting rope net and a rope connecting device, wherein the hexagonal extensible truss comprises top hinges, a synchronous power hinge, annular rods, and middle slanting poles; two annular rods with the same length form asynchronous folding rod through the synchronous power hinge, and the synchronous power hinge is connected with two middle slanting poles through three top hinges to form a planar triangle structural unit; 12 planar triangle structural units are connected with one another by sharing the middle slanting poles and the top hinges to form a ring, namely the truss of the antenna reflector modular unit;during connection, synchronous folding rods of two adjacent triangle structural units are spatially staggered with each other, and two layers of hexagons with different sizes and staggered vertexes are formed spatially; the reflecting rope net comprises a metal net for reflecting electromagnetic waves and an adjusting rope for adjusting the shape surface of the metal net; the metal net is sewed on the adjusting rope which is fixed with the truss of the modular unit through the top hinges; and the rope connecting device is mainly used for connecting and fixing the reflecting rope net and the hexagonal extensible truss.

Description

technical field [0001] The invention relates to a module unit of a large space assembled antenna reflector and an assembly method thereof, belonging to the technical field of satellite antenna reflectors. Background technique [0002] The geometric envelope space of the launch vehicle and the installation size of the satellite constrain and limit the application of super-large-aperture antennas on satellites to a certain extent. This problem can be solved by using space-assembled antenna technology. [0003] The basic composition of the space-assembled antenna includes: a space-assembled reflector, a large extension arm, and a large feed array. Among them, the space-assembled reflector is the core part of the space-assembled antenna. [0004] The space-assembled reflector adopts modular units with independent deployment functions, and the modular units are deployed and assembled on the rail in a certain order, and the integrated assembly forms a space truss structure with a ...
