Manned spacecraft extravehicular maintenance ground simulating system

Abstract

Provided is a manned spacecraft extravehicular maintenance ground simulating system. The system comprises a servo mechanism, a control platform, a vacuum tank, an observation window, spacesuit gloves and a support guide rail. The servo mechanism comprises a base, a stand column, a slide plate and a rotary platform. The base of the servo mechanism is fixed to the support guide rail, and the stand column is installed on the base and can move in the axial direction of the vacuum tank; the slide plate is installed on the stand column and can move in the perpendicular direction; the rotary platform is installed on the slide plate, and can move in the direction vertical to the axial direction of the vacuum tank within a horizontal plane; the rotary platform is internally provided with a motor connected to a rotary disc, the rotary disc is provided with a cross notch which can fix a maintenance equipment imitation part, and the motor rotates to drive the maintenance equipment imitation part to roll; the observation window and the spacesuit gloves are arranged on the vacuum tank. Through the manned spacecraft extravehicular maintenance ground simulating system, the maintenance equipment imitation part can be placed in the vacuum tank, and when the internal and external pressure difference of the spacesuit gloves is simulated, it is simulated that in-orbit extravehicular maintenance experiments are supported for a manned spacecraft when the relative position of the experiment personnel and the maintenance equipment imitation part are arbitrary.

Description

technical field [0001] The invention specifically relates to a ground 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 space station is a spacecraft that has people living in orbit for a long time. my country is developing the Tiangong space station, which is designed to have an in-orbit life of more than 10 years. It is my country's first large-scale manned spacecraft that has been in orbit for a long time. The permanent space stations currently in orbit include Russia's Mir space station and the International Space Station led by the United States. The design life of the Mir space station is 5 years, which can be extended to 15 years through on-orbit maintenance. The design life of the International Space Station is 15 years, and the life can be extended to 20 years through mainten...

Problems solved by technology

[0004] The problem solved by the present invention is to provide a low-cost ground simulation system for manned spacecraft maintenance outside the cabin, fix the on-orbit maintenance equipment on the system of the present invention, and put it into a vacuum tank with spacesuit gloves , under the condition of simulating the pressure difference between the inside and outside of the space suit glove, the simulation of any relative position between the test personnel and the on-orbit maintenance equipment can be realized, which overcomes the inability of the previous on-orbit extravehicular maintenance test method to simulate the pressure difference between the test personnel and the inside and outside of the space suit glove. Insufficient maintenance of any relative position of equipment
