Abstract

The invention relates to the research field of a microgravity simulating platform of a space robot, in particular to a microgravity air floatation target satellite simulator system with five degrees of freedom. The system consists of three parts, namely a movement simulator, a satellite simulator and a ground control panel. The movement simulator simulates the states of zero gravity, low friction and micro interference of a base satellite; the satellite simulator has a basic single-shaft attitude adjustment and track control function under a condition that a satellite provided by the movement simulator is in a track movement simulating environment, comprises a sensor, a controller and an actuating mechanism (a counteractive flywheel and a cold gas injecting system), and is provided with auxiliary systems such as a power system, a wireless communication assembly, a structural component and the like; and the ground control panel provides a basic function of the wireless data communication between a target satellite and the ground, and realizes the control on the target satellite and the receiving, storage and display of the data.

Description

technical field [0001] The invention relates to the research field of a microgravity air floating platform. Background technique [0002] With the continuous development of the space industry, space operation tasks have become more and more arduous and complex, such as the construction, service and maintenance of satellites in orbit or large space stations. It is far from enough for astronauts to complete these tasks, and the activities of astronauts out of the cabin are not only costly, but also have great dangers due to the influence of strong space radiation, high temperature difference and ultra-vacuum space environment, so the use of space manipulators It is necessary to replace or assist astronauts to complete these tasks. Participating in space activities, the space manipulator system can improve operating efficiency and save space operating costs on the basis of ensuring the safety of astronauts. Therefore, the space manipulator system will play an increasingly imp...
