[0002] The satellite feed is installed at the end of the deployment mechanism and enters the working state after being deployed in orbit. When working, the feed emits high-power microwaves through the horn. The high-power microwaves reach the target area through the antenna reflection surface to generate echoes. The satellite processes the echoes to generate images. The satellite feed is the main payload of the satellite. It needs to simulate the on-orbit working state during the satellite electrical performance test. High-power microwave radiation will be generated during the test, which will affect the occupational health and safety of surrounding workers. The high-power microwaves emitted by the satellite feed can be absorbed by the absorbing box, which can greatly reduce the risk of microwave radiation. Therefore, During the satellite electrical performance test, a satellite feed and an absorbing box need to be placed next to the satellite and assembled and positioned to ensure that the microwave radiation is controllable. The weight of the satellite feed is about 60kg, and the weight of the absorbing box is about 300kg. The length of the satellite feed head entering the absorbing box is not less than 150mm, and it cannot interfere with the absorbing material inside the absorbing box. This requirement can be achieved with the help of thermal test tooling, but the assembly process of the tooling is complicated, there is no adjustment, it needs to be repaired on site, the assembly repeatability is poor, the assembly cannot be moved flexibly, it is inconvenient to use in daily electrical performance testing processes, and it cannot adapt to changes in different test sites.

[0003] Therefore, it is urgent to design a satellite feed and absorber box on-site test device and assembly method. Based on the needs of improving assembly reliability and test site adaptability, a satellite feed and absorber box on-site test device is designed to reliably assemble the satellite feed and absorber box, simulate the on-orbit electrical performance test, and adapt to different test scenarios to ensure the occupational health and safety of personnel.

[0077] 3. The connection between the crossbar and the first fixing part, the second fixing part, and the connection between the first fixing part, the second fixing part and the satellite feed source of the present invention are all realized by adjusting the assembly allowance through waist-shaped holes and assembly sequence design, which reduces the precision requirements of the machining process, avoids the risk of failure to connect during on-site assembly, and improves the reliability of assembly;

[0078] 4. Based on the dimension chain design between the feed tooling and the vehicle body, the height dimensions of the satellite and the absorber box are controlled by using gaskets, which improves the flexibility and reliability of on-site assembly and ensures the smooth implementation of the assembly task;

[0079] 5. The present invention installs a baffle assembly on the bottom plate to position the absorbing box laterally, and cooperates with the positioning pin to ensure the limit design requirements between the absorbing box and the satellite feed source. The baffle assembly also realizes the lateral fixation and locking of the absorbing box, improves the overall stability of the assembly, and effectively achieves the anti-overturning requirements;

[0080] 6. The present invention realizes stable coordination between the wave absorbing box and the satellite feed assembly, which can meet the test state requirements of different test sites;

[0110] Fixed wheels 81 and universal wheels 82 are respectively installed at the two ends of the bottom of the bottom plate 31, and supporting mechanisms 7 are installed on the outer sides of the two groups of long sides of the bottom plate 31. In the early and late stages of the test process, the vehicle body 3 needs to be propped up away from the ground, and this operation needs to be completed through the supporting mechanism 7. The supporting mechanism 7 has a fixed plate 71, a threaded screw 72, a rotating handwheel 73, and a supporting cushion block 74. The fixed plate 71 is fixedly connected to the two sides of the long side of the bottom plate 31, and the fixed plate 71 is spirally connected to the threaded screw 72. The threaded screw 72 can move up and down the fixed plate 71.

First, the support frame 32 of the car body 3 needs to bear the weight of the feed tooling 5 and the satellite feed 1. At the same time, the guide assembly 6 is arranged on the support frame 32. The guide assembly 6 is used in conjunction with the feed tooling 5. The guide assembly 6 can limit the falling position of the feed tooling 5 and the satellite feed 1 to avoid collision with the satellite feed 1. At the same time, the guide assembly 6 cooperates with the feed tooling 5 to adjust the relative height of the satellite feed 1 and the internal structure of the absorbing box 2. Specifically, the support The frame 32 has a crossbeam 321 and a vertical beam 322, the vertical beam 322 is perpendicular to the bottom plate 31, and the crossbeam 321 is vertically connected between the vertical beams 322.

Because the mounting hole 531 on the second mounting plate part 53 is a waist-shaped hole, the waist-shaped hole has an adjustable space, and the second fixing part 55 can be properly adjusted in position during the installation process.

[0115] A method for assembling a satellite feed and a wave absorbing box satellite-side test device comprises the following steps:

[0116] Step 1: Select a suitable site, lift and support the vehicle body 3 through the support mechanism 7, use the hand wheel 73 to rotate the threaded screw 72, the threaded screw 72 gradually touches the ground downward and supports the vehicle body 3, and the support height is based on the fixed wheel 81 and the universal wheel 82 leaving the ground;
