Embodiment 1

[0039] A multi-dimensional dynamic microgravity environment simulation system for large space motion loads, such as figure 1 As shown, it is a structural schematic diagram of a multi-dimensional dynamic microgravity environment simulation system for large-scale space motion loads according to the present invention. The system includes: lifting frame body 1, turning table 2, installation platform, gravity balance mechanical arm 3 and auxiliary support components 4.

[0040] The lifting frame body 1 is a spliced ​​type lifting frame body, which can be assembled according to the required height, and provides a mounting surface for the gravity balance mechanical arm 3 and the space movement load.

[0041] The top of the lifting frame body 1 is fixedly provided with a gravity balance mechanical arm 3, and the lifting frame body 1 is also provided with a slider, which can slide along the vertical direction of the lifting frame body 1. Such as figure 2As shown, it is a schematic s...

Embodiment 2

[0049] A multi-dimensional dynamic microgravity environment simulation method for large-scale space motion loads, the method includes:

[0050] Construct a microgravity environment through a gravity-balanced robotic arm;

[0051] During the closed-loop test, the auxiliary supporting parts are put away on one side of the lifting frame body, which does not affect the system test; when the test is over, the auxiliary supporting parts are supported at a reasonable position of the moving load by the supporting screw to offset the gravity balance machine The residual weight of the moving load after the arm is suspended, and the degree of residual weight offset is judged by the rope tension measuring instrument on the gravity balance mechanical arm. When the suspension force and antenna weight displayed by the hanging rope tension measuring instrument are within mN, it is considered Completely offset, the value of the variable m depends on the static friction moment of the space load...

The method and system of the invention realize more stable, reliable and safe simulation of multi-dimensional dynamic microgravity.

Description

technical field [0001] The invention relates to a microgravity environment simulation system, in particular to a multi-dimensional dynamic microgravity environment simulation method and system. Background technique [0002] Ground microgravity simulation is a new research field emerging with the development of aerospace technology. Compared with digital simulation and theoretical evaluation, the test data obtained through microgravity simulation is more authentic and reliable, and has irreplaceable advantages. Therefore, in order to ensure the reliability of the spacecraft's in-orbit operation, the microgravity ground simulation test is an essential work. [0003] In the field of space security, with the continuous emergence of multi-functional, multi-band, long-distance and other multi-functional multiplexed loads, it is inevitable that large-scale space motion loads will appear in the load structure. The large weight, large size, high cost, and extremely small samples of ...
