Description

Technical Field

[0001] This invention belongs to the field of aerospace scenario simulation and deduction technology, specifically relating to a three-dimensional simulation platform that supports space-ground collaborative orbit control. Background Technology

[0002] The technology for simulating and extrapolating space orbit control scenarios is still in its infancy, particularly lacking a three-dimensional, manual simulation device that supports coordinated space-ground orbit control. Current manual orbit control simulations primarily rely on two-dimensional simulation platforms or devices. These platforms not only lack an intuitive three-dimensional space but also fail to fully consider the collaborative effects of space-ground equipment, thus failing to meet the current needs of space orbit control research and demonstration. Summary of the Invention

[0003] To address the current challenge of lacking three-dimensional simulation and deduction methods for aerospace equipment configuration and orbit control, this invention provides a three-dimensional simulation platform that supports space-ground coordinated space orbit control. This platform can present the equipment deployment status, display the space orbit orientation, and realize dynamic control simulation, which is conducive to further supporting related research, teaching, and simulation training activities. It is suitable for aerospace-related units to carry out research, teaching, and simulation training on space-ground equipment deployment, space mission planning, and orbit control strategies.

[0031] The production process of the aforementioned 3D simulation platform includes the following steps: Fabrication of Bracket 1: Bracket 1 consists of two independent components: a scissor-type movable bracket 11 and a plug-in positioning frame. The upright of the scissor-type movable bracket 11 is made of a Φ100×3mm round tube, and the crossbeam of the scissor-type movable bracket 11 is made of an 80×60×2mm square tube. The square frame 13 in the plug-in positioning frame is made of a 60×40×2mm square tube.

Reinforcing plates made of 3mm thick steel plates can be set at the inner corners of the square frame 13.

[0032] Countertop 2 Construction: Countertop 2 construction should be carried out in layers. First, a bottom layer with a diameter of 2472mm is made using 20mm thick plywood 24. To reduce its weight, a 900×900mm hole can be left in the middle. Then, 80mm wide plywood 24 reinforcing strips and limiting strips are added to the back perimeter of the bottom layer and the four sides of the support 1 position. After the bottom layer is completed, its dimensions and flatness should be checked. Only after it passes the inspection can the upper layer be constructed. The upper layer uses 16mm thick plywood 22. First, install a circular upper panel with a diameter of 1778mm at the center of the panel. Then, install the inner annular pulley track. Secure the inner annular pulley track (made of 28×2mm flat steel) laterally along the perimeter of the circular panel using screws. After the inner annular pulley track is installed correctly, fabricate and fix the panel between the inner and outer annular pulley tracks 5. Then, install and fix the outer annular pulley track 5. After completing the installation of the outer annular pulley track 5, complete the upper panel outside the track. The upper panel should be the same size as the bottom panel. Finally, install the surface layer of tabletop 2. Except for the map placement area in the center of tabletop 2, which uses a 2mm thick magnetic panel 23, all other surfaces of tabletop 2 and its perimeter are covered with 4mm thick aluminum composite panels 21 as the surface layer. (Refer to [reference needed]). Figure 7 , Figure 8 and Figure 9 .

[0033] Space frame fabrication: First, the casters 33 and the suspension connecting plate must be fabricated. Casters 33 are available in single-wheel and double-wheel structures, such as...

Figure 18 and Figure 19As shown; among them, the traveling wheel 332 is a U-groove nylon wheel with bearings, the shaft insertion tube of the suspension connecting plate is a Φ16×2.5mm steel pipe, and the others are made of 2mm thick steel plates, which are welded together to form... Figure 18 and Figure 19 Structure. After the casters 33 and the suspension connecting plates are completed, the space frame is fabricated. The space frame uses 5mm thick high-transparency acrylic sheets. According to the diagram, the fan-shaped panels are processed and covered with transparent magnetic film. The suspension connecting plates are then installed on top. It is important to ensure that the suspension connecting plates of each space frame are staggered in the height direction. Finally, the casters 33 are installed on the space frame. The outer ring (high rail) frame uses double-wheel 332, and the inner ring (medium / low rail) frame uses single-wheel 332. According to the plan, one double-width direct-connection inner and outer ring space frame and two single-width inner and outer ring space frames are required.

[0034] Operator manufacturing: Operators can be customized directly from professional manufacturers according to requirements.

[0035] Once each unit component is manufactured, it can be assembled without any tools; simply stack them from bottom to top: First, unfold the movable support 1 and insert the insert-type positioning frame. Then, place the platform 2 on the support 1 and align it with the limiting strips of the support 1 on the bottom surface of the platform 2. Next, install the spatial frame: first, install the double-width straight-connected outer ring (high rail) frame, then install the single-width outer ring (high rail) frame, and finally install the inner ring (medium / low rail) frame. Place the outer ring frame 4 on the outer annular pulley track 5 of the platform 2, and the inner ring frame 3 on the inner annular pulley track. Then, insert the vertical suspension shaft 6 of the central suspension shaft from top to bottom, thus completing the manufacture and assembly of the spatial track control 3D simulation platform.
