Description

technical field [0001] The invention belongs to the technical field of digital manufacturing, and relates to a satellite intelligent assembly process planning system. Background technique [0002] In modern high-tech warfare, satellite core military equipment will assume an increasingly important role in national defense. Develop a new generation of military remote sensing satellites, a new generation of military communication relay satellites, and a new generation of navigation satellites, etc., and have performance requirements such as high spatial resolution, high time resolution, high spectral resolution, and high target positioning accuracy. The development progress also puts forward urgent demands. [0003] In the satellite development process, satellite assembly is the final stage and key link in the realization of satellite product functions and performance, and it is also a difficult point that needs to be optimized urgently. First of all, the satellite assembly c...

Problems solved by technology

The manpower required for assembly accounts for about 40% of skilled labor, and more than 40% of production costs are used for product assembly, and the manual labor of assembly work is relatively large

Secondly, the assembly process of the satellite model structure is complicated, the quality requirements are high, and the requirements for the guidance ability of the assembly process refinement and quantification are getting higher and higher

Taking the XX satellite as an example, the satellite has greatly improved and improved in terms of imaging resolution and imaging accuracy. The deployment length of its antenna wings reaches 56m. Relational matching requirements are high. Trial assembly, precise measurement and debugging are required for multiple links in assembly, and multiple tests and experiments are required for final performance. The current assembly process simulation methods, manual assembly and adjustment methods, and ordinary laser tracker theodolite online measurement methods can no longer meet the demand,
