Embodiment Construction

[0028] The following is a specific implementation manner of the content of the present invention, and the content of the present invention will be further clarified through the specific implementation mode below. Of course, the following specific embodiments are described only to illustrate different aspects of the present invention, and should not be construed as limiting the scope of the present invention.

[0029] refer to Figure 1-3 , the test brackets suitable for different installation surfaces, that is, side, top and bottom surfaces are given respectively, and the test brackets are selected according to the type of installation surface. The top surface uses a 45° test bracket, the side uses a 22.5° test bracket, and the bottom surface uses a 0 ° or 45° test bracket; 45°, 22.5° and 0° test brackets are respectively 45°, 22.5° and 0° to the docking surface of the special-shaped satellite and the docking surface of the test equipment. figure 1 Corresponding to the 45° t...

Abstract

The invention discloses an attitude-adjusting assembly process for antenna performance test of a special-shaped satellite structure. The attitude-adjusting assembly process includes determining a fitting surface of the special-shaped satellite structure, selecting a test support according to the type of the fitting surface, fixedly connecting the selected test support to test equipment and adjusting a butt-joint surface of the test support and a special-shaped satellite into a horizontal or vertical state, assembling two single-beam double-lifting-point turnover slings to realize 90-degree turning of the special-shaped satellite, assembling a single-beam four-lifting-point horizontal sling to lift the satellite to the butt-joint surface matched with the test support and then connecting the satellite and the test support fixedly, thereby testing the antenna performance. By means of combination of the slings and different types of test supports, the essential problem in satellite attitude adjustment is solved, and tests of different types of antennas are completed.

Description

technical field [0001] The invention belongs to the technical field of tooling for attitude adjustment of spacecraft. Specifically, the invention relates to an attitude adjustment assembly process for performance testing of special-shaped satellite structure antennas. Background technique [0002] Antenna is an important component of a satellite, and a satellite conducts a special test to test the performance of the antenna. There are three types of test antennas, which are distributed on different installation surfaces of the satellite. Since the installation angles of each antenna are different and the test orientations are different, different test brackets need to be equipped to meet the test attitude requirements. During the test of various antennas, it is necessary to use the spreader to turn over and hoist the satellite horizontally to adjust the attitude and install and dock with the test bracket of each test antenna. The attitude adjustment of the satellite during ...
