Problems solved by technology
The assembly stress caused by gravity cannot be eliminated, which will not only lead to out-of-tolerance assembly accuracy of the product, but also force the stress-concentrated parts, which will eventually affect the unfolding performance and accuracy of the product; at the same time, the assembly stress also directly affects the accuracy of the folded state of the product. The docking installation of the product and the star poses hidden dangers
In the process of product debugging, because there is no control measure for precise adjustment of each degree of freedom, the phenomenon of overshoot and repetition often occurs in the debugging process, which seriously reduces the assembly efficiency and prolongs the product development cycle

Description
technical field [0001] The invention relates to an integrated device for posture adjustment and unloading efficiency detection, in particular to an integrated device for posture adjustment and unloading efficiency detection for zero-gravity assembly of a space deployment mechanism, and a ground zero-gravity device for a space deployment mechanism with high precision and complexity The unloading assembly belongs to the technical field of precision assembly of space expandable mechanisms. Background technique [0002] Zero gravity, also known as weightlessness or reduced gravity, is one of the most important features of the space environment. Before space systems such as satellites, aircraft and space stations fly in orbit, in order to ensure the high precision and reliability of the system, it is necessary to conduct dynamic tests on the subsystems of the space mechanism on the ground. However, the gravitational environment of the ground makes it impossible to obtain the per...
