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

[0050] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. In addition, all directions or positional relationships (such as "up", "down", "front", "rear", "left", and "right" mentioned in the embodiments of the present application are based on the drawings. The positional relationship is only for facilitating the understanding of the application and simplifying the description, rather than implying the specific orientation that the device or element referred to must have, and cannot be understood as a limitation of the application.

[0051] The present invention aims to protect an angle and eccentricity adjustment device, which is a component of the suspension hoisting mechanism, which can adjust the yaw angle and eccentric position of the suspension target to meet different test requirements ; In order to facilitate a clearer description of the angle and eccentricity adjustm...

Abstract

The invention provides an angle and eccentricity adjusting device and a microgravity rollover state simulation system, and relates to the technical field of on-orbit service and maintenance. The angleand eccentricity adjusting device is suitable for hoisting a suspension target and adjusting the deflection angle and the eccentric position of the suspension target; the angle and eccentricity adjusting device comprises a first target transferring plate, a second target transferring plate, a lead screw and a lead screw nut seat; the second target transferring plate is oppositely arranged on thelower side of the first target transferring plate and fixedly connected with the suspension target; the lead screw is horizontally arranged at the bottom of the first target transferring plate in theaxis direction of the lead screw; the lead screw nut seat is arranged on the outer side of the lead screw in a sleeving mode; and the lead screw nut seat is directly or indirectly connected with the second target transferring plate and is suitable for driving the second target transferring plate and the first target transferring plate to relatively move. According to the angle and eccentricity adjusting device, the deflection angle and the eccentric position of the suspension target can be adjusted, and the different test needs are met.

Description

Technical field [0001] The invention relates to the technical field of on-orbit service and maintenance, in particular to an angle and eccentricity adjustment device and a microgravity roll state simulation system. Background technique [0002] The geostationary orbit (GEO) is an important earth orbit resource for mankind. On-orbit resources are limited by the orbital position and are extremely scarce. However, with the rapid development of space missions, the GEO zone (GEO±200km) has accumulated many uncontrollable or obsolete satellites. These satellites have caused a serious waste of GEO orbital resources. For satellites that fail in orbit, in terms of attitude characteristics, due to the energy dissipation effects of the solar wing and propellant shaking of the stars, they will eventually show a rolling attitude, and it is a major difficulty to capture them in orbit. In order to solve this difficulty, it is urgent to carry out research on key technologies related to on-orbit...
