Problems solved by technology

[0005] For the radar antenna board with a large span in the retracted state, if the traditional metal continuous rod + taper sleeve scheme is used, on the one hand, the spacecraft structure cannot withstand excessive mechanical loads; on the other hand, the metal continuous rod cannot be pulled away when the antenna is deployed, resulting in deployment failure.

Embodiment 1

[0049]The antenna board position-limiting pressing system provided by the present invention includes a frame structure, an antenna board 7, and a pressing taper sleeve array 6; ; The inside of the main body truss 1 forms a storage space. The pressing taper sleeve array 6 includes a plurality of series of taper sleeves with male and female interlocking, and a plurality of taper sleeves are detachably arranged; the antenna board 7 is installed on the taper sleeves. Antenna board limit type compression system can switch between the two states of folded state and unfolded state: such as figure 2 As shown, in the folded state, the antenna board 7 is located in the storage space as a whole; image 3 As shown, in the unfolded state, the antenna board 7 can reach a space other than the storage space.

[0050] The multiple taper sleeves include tail taper sleeves 67, inter-board taper sleeves, and head taper sleeves 65 arranged in sequence; the tail taper sleeves 67 are installed on...

Embodiment 2

[0056] Such as figure 2 , image 3 As shown, the unfolded truss 2 is provided with five parallel bars from top to bottom, and the two ends of each bar are connected to the main truss 1 by separating nuts 3 to form a closed cage structure surrounding eight antenna panels 7 . The unfolding hinge 5 is arranged on the vertical bars of the main body truss 1 and the unfolding truss 2, and opens the unfolding truss 2 after the release nut 3 is unlocked. Five pressing points are arranged symmetrically on both sides of the antenna plate 7, corresponding to the five cross bars of the unfolded truss 2; a set of pressing force loading measurement device is set at the pressing points of each cross bar of the unfolded truss 2. The eight antenna boards 7 are connected at each pressing point with a pressing taper sleeve array 6 composed of a series of taper sleeves, in which the head taper sleeve 65 is connected with the pressing force loading measurement device, and the tail taper sleeve 6...

Embodiment 3

[0059] The present invention also provides a method for limiting and pressing the above-mentioned antenna plate, including the following steps: Step S1: Install the loading device 4 and the axial force sensor 47 on the unfolding truss 2; Step S2: Install the main truss 1 and The deployment truss 2 is connected by the deployment hinge 5, so that the deployment hinge 5 is kept open relative to the main body truss 1; Step S3: connect a plurality of taper sleeves in series to form a compression rod 6, wherein the tail taper sleeve 67 is installed on the main body truss 1, and the head The taper sleeve 65 is installed on the unfolded truss 2; step S4: fasten the antenna board 7 on the inter-board taper sleeve, and each antenna board 7 is folded into the main truss 1 sequentially through the inter-board hinge; step S5: close Expand the truss 2, and fix the main body truss 1 and the expanded truss 2 through the separation nut 3, so that the antenna board position-limiting pressing sys...

Abstract

The invention relates to an antenna plate limiting type pressing system and an application method in the technical field of antennas. The system comprises a frame structure, an antenna plate and a pressing taper sleeve array. The frame structure comprises a main truss and an unfolded truss, and the main truss is movably connected with the unfolded truss. A storage space is formed in the main truss; the pressing taper sleeve array comprises a plurality of taper sleeves, and the plurality of taper sleeves are detachably arranged; the antenna plate is mounted on the taper sleeves; the antenna board limiting type pressing system can be switched between a folded state and an unfolded state, in the folded state, the whole antenna plate is located in the storage space, and in the unfolded state,the antenna plate can reach the space outside the storage space. Reliable pressing and releasing of the large planar antenna are achieved through the deployable satellite truss and the pressing tapersleeve array, and the problem of installation and integration of a large satellite-borne radar on a satellite platform is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna board position-limiting pressing system and a method thereof. Background technique [0002] Since the middle of the last century, the United States, Europe, the former Soviet Union and other countries have started the development of spacecraft antenna drive mechanisms with the strong support of the industrial sector. At present, spacecraft antenna drive mechanisms have been widely used in various spacecraft, such as relay Satellites, communication satellites, various detectors, remote sensing satellites, space stations, reconnaissance satellites, etc. After decades of development, there are various types of space drive mechanisms with different performances and wide applications, which have become serialized and have high reliability. The servo mechanism system for the radar load has also developed rapidly with the development of the drive mechanism, and it w...
