Description

Technical Field

[0001] This invention relates to the field of spacecraft ground magnetic levitation separation test technology, specifically to a magnetic levitation separation support device for satellite payload compartments. Background Technology

[0002] During the magnetic levitation separation test between the satellite payload compartment and the platform compartment, the payload compartment needs to be air-floated on the marble platform to verify the pointing accuracy of the load inside the payload compartment. Because the payload compartment side panels themselves are made of carbon fiber honeycomb structure, which is relatively weak and easily deformed, and because the side panels lack an interface for installing air-floating pads, a support unloading device needs to be designed to connect with the payload compartment floor plate to simulate the payload compartment and install air-floating pads for unloading onto the marble platform. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a magnetic levitation separation support device for satellite payload compartments.

[0004] According to the present invention, a magnetic levitation separation support device for a satellite payload compartment includes a main support frame and upper support leg, lower support leg, left support leg and right support leg respectively vertically arranged at the upper end, lower end, left end and right end of the main support frame;

[0005] The lower support leg is provided with a first air cushion mounting column and a second air cushion mounting column. The main support frame has an octagonal outline and a third air cushion mounting column arranged in the same direction as the first air cushion mounting column and the second air cushion mounting column on the lower end side.

[0006] Preferably, the main support frame is equipped with multiple gas cylinder mounting plate fixing structures.

[0007] Preferably, both the upper support leg and the lower support leg are adjustable vertically on the main support frame;

[0008] The left and right support legs are both adjustable left and right on the main support frame.

[0009] Preferably, the main support frame is provided with an upper support leg mounting surface, a lower support leg mounting surface, a left support leg mounting surface, and a right support leg mounting surface, respectively, for mounting the upper support leg, the lower support leg, the left support leg, and the right support leg.

[0010] Preferably, the upper support leg mounting surface, lower support leg mounting surface, left support leg mounting surface, and right support leg mounting surface are each provided with multiple mounting holes.

[0011] Preferably, the upper support leg, lower support leg, left support leg, and right support leg each have a first connection structure that matches a plurality of the mounting holes.

[0012] Preferably, the upper support leg, lower support leg, left support leg, and right support leg are each provided with a second connecting structure at the end away from the main support frame.

[0013] Preferably, both the left and right support legs are equipped with lifting rings.

[0014] Preferably, the upper support leg, lower support leg, left support leg, and right support leg are each provided with a load compartment connection end at the end away from the main support frame.

[0015] Preferably, the upper support leg, lower support leg, left support leg, and right support leg are all I-shaped structures.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] During satellite maglev tests, this invention is fixedly connected to the payload compartment floor to simulate the payload compartment body. The air-bearing pad mounting column below the support device connects to the air-bearing pad, providing air-bearing support for the payload compartment on the air-bearing platform. Because the four support legs of the support device all adopt an I-beam structure, the structure is simple, and the entire support device is made of stainless steel. Finite element analysis shows that the deformation of the fixed assembly between the support device and the payload compartment floor is small, ensuring stability and reliability during unloading. This avoids wasted time due to rework and repairs, and improves the efficiency of maglev separation of the satellite payload compartment. Therefore, this invention improves the support stiffness of the satellite payload compartment in maglev separation tests, and has advantages such as simple structure, small deformation, and safety and reliability.
