A ground all-element simulation system for extravehicular maintenance of manned spacecraft

Abstract

An extravehicular maintenance ground total-factor simulation system for a manned space vehicle comprises a servo mechanism, a console, a vacuum tank, an observation window, spacesuit gloves, support guide rails, a vacuum cold-dark environment simulation subsystem, a thermal simulation subsystem, an equipment state simulation subsystem and an illumination simulation subsystem. The servo mechanism can achieve horizontal movement, vertical movement and rotation of a maintenance equipment simulation part installed on the servo mechanism, the vacuum cold-dark environment simulation subsystem can simulate the extravehicular vacuum cold-dark environment, the thermal simulation subsystem can simulate the extravehicular temperature environment, the equipment state simulation subsystem can simulate the working state of the maintenance equipment simulation part, and the illumination simulation subsystem can simulate the extravehicular illumination environment. When simulating the on-orbit extravehicular vacuum cold-dark environment, thermal, illumination and equipment working state, the extravehicular maintenance ground total-factor simulation system for the manned space vehicle simulates the pressure difference between the inside and the outside of the spacesuit gloves and the relative position between test personnel and the maintenance equipment simulation part, and thus on-orbit extravehicular maintenance ground total-factor simulation for the manned space vehicle is achieved.

Description

technical field [0001] The invention specifically relates to a ground all-element simulation system for extravehicular maintenance of manned spacecraft, which is suitable for ground tests of extravehicular maintenance of manned spacecraft and belongs to the field of manned spacecraft tests. Background technique [0002] 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. After the International Space Station is assembled, a total of 39 tons of maintenance spare parts will be delivered to the International Space Station, including about 22 tons of extravehicular spare parts. As of September 2016 , A total of 384 out-of-cabin maintenance were carried out. Judging from the construction and operation experience ...

AI Technical Summary

Problems solved by technology

2. The human-machine characteristics have a complex impact on out-of-cabin maintenance during maintenance

3. There are many products and interfaces that need to be maintained outside the space station, making it difficult to verify coverage

4. The orbital operation guarantee of the space station is complex and has high requirements for rapid response
