Multi-segment-type guiding and damping device applicable to space conical rod mechanism

Abstract

The invention provides a multi-segment-type guiding and damping device applicable to a space conical rod mechanism. The guiding and damping device is installed at the front end of the space conical rod mechanism and used for guiding and damping the movement of the conical rod mechanism on the inner wall of a conical structure to be in butt joint. The device comprises a device body, damping assemblies, a plurality of segment-type structures and a plurality of in-place sensors. Each segment-type structure is installed on the device body through the corresponding damping assembly. After the segment-type structures are combined, the whole segment-type structure is conical in shape, and the radian of the whole segment-type structure is slightly larger than that of the inner wall of the conical structure to be in butt joint so that one or two of the segment-type structures can firstly make contact with the inner wall of the conical structure to be in butt joint. The guiding and damping device can adapt to satellite capture under a weak impacting condition, large relative speed and angular speed tolerance can be provided for a capture mechanism, the contact mass, generated at the collision instant, of the conical rod mechanism is small due to the multi-segment-type structure, and energy can be faster absorbed by the damping device.

Description

technical field [0001] The invention belongs to the technical field of spacecraft on-orbit service, and in particular relates to a multi-lobe guide damping device used for a space cone-rod mechanism (such as a general capture and docking mechanism for high-orbit satellites). Background technique [0002] GEO satellites usually have the characteristics of large scale, multi-function, long life, and high cost. If a failure occurs in orbit and the mission cannot be completed normally, it will have a serious impact on the country's politics, economy, and other aspects. The development of rescue service capabilities for GEO satellites can quickly continue the mission capability of faulty satellites at a relatively low cost, or assist the de-orbiting of abandoned satellites to release important orbital resources, which can achieve very important economic and social benefits. [0003] Since the GEO satellites currently in orbit and under research are not designed to receive in-orbi...

Problems solved by technology

Unfortunately, the agency only considers the capture operation when the service aircraft and the target satellite are relatively stationary, and does not consider the use of the residual speed of the service aircraft during the relative docking process for capture, which has high requirements for the attitude and orbit control of the service aircraft itself , so there is no focus on installing a guide damping device on the cone-rod mechanism to buffer the energy of the capture and docking process
