Embodiment Construction

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

[0029] Reference Figure 1-3 , Respectively give test brackets suitable for different mounting surfaces, namely the side, top and bottom surfaces. The test brackets are selected according to the type of mounting surface. The top surface uses the 45° test bracket, the side uses the 22.5° test bracket, and the bottom surface uses 0 ° or 45° test stand; the interface between the test stand at 45°, 22.5° and 0° and the special-shaped satellite and the interface with the test equipment are respectively 45°, 22.5° and 0°. figure 1 Corresponding to the 45° test stand; figu...

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 spacecraft attitude adjustment. Specifically, the invention relates to an attitude adjustment assembly process used for testing the performance of a special-shaped satellite structure antenna. Background technique [0002] The antenna is an important component of the satellite, and a certain satellite conducts a special test to test the performance of the antenna. There are three types of test antennas, and they are distributed on different installation surfaces of the satellite. Because of the different installation angles and different test orientations of each antenna, different test brackets are required to meet the test attitude requirements. In the test process of various antennas, it is necessary to flip and hoist the satellite horizontally with a spreader to adjust the attitude and install and dock with the test bracket of each test antenna. Throughout the test, two sets of flipping spread...
