A ground rapid response support method for on-orbit maintenance of spacecraft

Abstract

The method provides a fast response and support method for the out-of-cabin in-orbit maintenance ground of a spacecraft cabin. The method comprises the steps of (1) providing a maintenance plan of the out-of-cabin fault equipment, wherein the maintenance plan comprises a maintenance transfer path, a maintenance operation process and a human-computer work efficiency evaluation standard; (2) establishing a three-dimensional model of a spacecraft cabin body, simulating the layout of all equipment outside the spacecraft cabin body, simulating and verifying the maintenance transfer path, judging whether the transfer path is blocked by external equipment or not; (3) testing and verifying the maintenance operation, recording the operation torque and the operation time; (4) judging whether the operation moment and the operation time conform to the human-computer work efficiency evaluation standard specified in the maintenance plan or not; (5) determining a maintenance scheme available for the out-of-cabin in-orbit maintenance of astronauts. Based on the method, the out-of-cabin equipment maintenance scheme of an in-orbit burst fault can be quickly determined. Therefore, the fast response capability within one hour can be realized. Moreover, the economical efficiency is excellent. The rapid verification problem of the large-mass external maintenance of a space station can be solved.

Description

technical field [0001] The invention relates to a ground rapid response support method for on-orbit maintenance outside the cabin of a spacecraft. The invention belongs to the technical field of overall design of manned spacecraft, and specifically belongs to the technical field of maintainability design and verification. Background technique [0002] my country's space station has a long orbital life and high reliability requirements, and its development is unprecedentedly difficult. The "Mir" space station has extended its lifespan to 15 years through maintenance, and 75% of the time during the life extension period astronauts are performing maintenance work. The life of the International Space Station will be extended to 2024 through maintenance. Astronauts spend 40% of their daily maintenance work. As of September 2016, a total of 384 out-of-cabin maintenance have been carried out. Maintenance is an indispensable key measure to ensure the operation of my country's space...
