Problems solved by technology

However, with the rapid development of space missions, many uncontrollable or abandoned satellites have accumulated in the GEO belt (GEO ± 200km), and these satellites lead to a serious waste of GEO orbital resources
For in-orbit failed satellites, in terms of attitude characteristics, due to energy dissipation effects such as star solar wings and propellant sloshing, they will eventually show a rolling attitude, and it is a major difficulty to capture them on-orbit

Embodiment Construction

[0054] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In addition, all directions or positional relationships (such as "upper", "lower", "front", "backward", "left", "right") mentioned in the embodiments of the present application are based on the drawings The positional relationship is only for the convenience of understanding the application and simplifies the description, and does not imply a specific orientation that the referred devices or elements must have, and should not be construed as limiting the application.

[0055] The present invention aims to propose a suspension upswing mechanism to realize the ground simulation of the rolling attitude of the target under the state of space microgravity, so as to verify the rationality and technical feasibility of the space task scheme on the basis of the ground test.

[0056] The present invention will be descri...

Abstract

The invention provides a suspension spinning mechanism and a microgravity rolling state simulation system, which relate to the technical field of on-orbit service and maintenance, including: a spinning device, which is suitable for causing a suspended target to spin around a spin axis; A flexible constraint switching device, which is suitable for switching between rigid constraints and flexible constraints between the suspension upswing mechanism and the suspended target; an angle and eccentricity adjustment device, which is suitable for the deflection of the suspended target Angle and off-center position adjustments. The suspension up-spin mechanism of the present invention can not only realize the spin of the suspended object around the spin axis, but also realize the swing of the spin axis of the suspended object, and arbitrarily switch the rigid constraint state and the flexible constraint state of the suspended object , so as to realize the ground simulation of a possible attitude roll state of a faulty satellite in orbit.

Description

technical field [0001] The invention relates to the technical field of on-orbit service and maintenance, in particular to a suspension spinning mechanism and a microgravity rolling state simulation system. Background technique [0002] Geostationary Orbit (GEO) is an important earth orbit resource for human beings, and the on-orbit resources are limited by the orbital position and are extremely scarce. However, with the rapid development of space missions, many uncontrollable or abandoned satellites have accumulated in the GEO belt (GEO ± 200km), which leads to a serious waste of GEO orbital resources. For in-orbit failed satellites, in terms of attitude characteristics, due to energy dissipation effects such as star solar wings and propellant sloshing, they will eventually show a rolling attitude, and it is a major difficulty to capture them on-orbit. In order to solve this difficulty, it is urgent to carry out research on key technologies related to on-orbit service and m...
