A microgravity simulation device for tumbling characteristics of large space targets

Abstract

A microgravity simulation device for rolling characteristics of a large space target comprises a bottom base, mechanical arms and a target simulator, wherein bases of the mechanical arms are fixed onthe bottom base; ends of the mechanical arms are provided with ball bearings; the mechanical arms support the target simulator through the ball bearings; the target simulator is used for simulating the 6DoF microgravity motion characteristics of space debris, and used for acquiring self position and attitude data in real time and feeding the data back to the mechanical arms; and the mechanical arms adjust the motion speeds of joints and the positions of the ball bearings at the ends in real time according to the self position and attitude data fed back by the target simulator so as to achievethe ground demonstration and verification of the speed, position and attitude control of the target simulator. The microgravity simulation device for the rolling characteristics of the large space target can simulate the 6DoF microgravity motion characteristics of the large-size and heavy-weight space target in the space, and can achieve the ground demonstration and verification of multi-arm combined manipulation on the space debris target.

Description

technical field [0001] The invention relates to a microgravity simulation device for tumbling characteristics of a large space target, belonging to the field of space debris removal. Background technique [0002] Space debris poses a great threat to human space resource development activities. In order to safely and continuously develop and utilize space resources, it is necessary to find effective measures to control and mitigate space debris. At present, the measures for controlling and mitigating space debris can be summed up as two main types: prevention and treatment. Prevention is to reduce the generation of space debris as much as possible during the launch and operation of spacecraft, and governance is to try to remove existing space debris in orbit. [0003] The ground test methods for space debris removal mainly include the parabolic flight method, the water float method, and the hanging wire suspension method. The traditional methods cannot cope with the microgra...
