Description

technical field [0001] The invention relates to a follow-up gravity compensation device, in particular to a follow-up gravity compensation device for a three-degree-of-freedom space station pan table lamp, which belongs to the field of aerospace. Background technique [0002] With the development of the aerospace industry and the continuous improvement of the level of science and technology, the enthusiasm for exploring the unknown areas of the universe has reached an unprecedented high. While space activities represent a country's comprehensive strength level, it is also a symbol of a powerful country. At present, the development process of space exploration activities is usually: orbiting satellites, space stations and space exploration. The detection mission requires high performance in all aspects of the system. The equipment entering space must first conduct corresponding experiments and a large number of performance evaluations on the ground, so as to ensure that the ...
