A high-precision vertical docking system for a large spacecraft

Abstract

The invention discloses a high-precision vertical docking system for a large-scale spacecraft. The upper cabin that reaches the docking position is hovered and fixed by the upper cabin hovering support adjustment system, and the docking accuracy measurement and monitoring system is used to implement non-destructive testing on the docking surface of the two cabins. Contact precision measurement and precision adjustment guidance, adjust the position accuracy of the lower cabin through the reverse docking attitude adjustment transfer system of the lower cabin to meet the accuracy requirements of the docking surface, implement micro-impact reverse docking to realize the precise docking of the lower cabin and the upper cabin, and adopt visual docking guarantee System and operation accessibility guarantee system to realize the operability of the docking process, minimize the risk of docking, and realize efficient, precise and stable docking of large and complex spacecraft. The system is easy to operate, has a simple implementation process, effectively controls the risk of large-scale spacecraft docking, improves assembly efficiency, and has strong versatility. It is applicable to docking of various cabin-type spacecraft structures and plays an important role in improving the accuracy and quality of spacecraft assembly.

Description

technical field [0001] The invention relates to the field of vertical docking of large spacecraft, in particular to a high-precision vertical docking system of large spacecraft. Background technique [0002] Based on the complex functional requirements of the spacecraft, the docking between the cabins is usually accompanied by difficulties such as high docking accuracy requirements, complex distribution of load units near the docking surface, and poor visualization and operability of the docking surface. Compared with horizontal docking, the vertical docking process is simple, the implementation cost is lower, the versatility is stronger, and it is more in line with the working state of the vertical launch of the spacecraft. Therefore, the vertical docking technology between large cabins has an irreplaceable role. [0003] At present, the vertical docking assembly of large spacecraft cabins still mostly uses hoisting or moving ground tooling to move the two sides of the dock...
