Buffering despinning damping device for satellite docking

Abstract

The invention discloses a buffering despinning damping device for satellite docking, comprising a split buffering structure and a despinning damping structure; the split buffering structure comprises a buffering body, a linear spring damper, a split structure and an arrival sensor; the despinning damping structure comprises a despinning body, a rotary transmission disc and a rotary motor. The buffering despinning damper is applicable to satellite capture under weak impact condition, and high relative speed and large angular speed tolerance can be provided for a capturing mechanism; the split buffering structure arranged in the damping device experiences collision buffering with the inner wall of an engine nozzle of a target satellite, and relative movement speed in the collision process is reduced; the spinning damping structure that drives the split buffering structure in rotation is provided, and the relative angular speed of the split buffering structure to the inner wall of the engine nozzle of the target satellite is thus reduced.

Description

technical field [0001] The invention relates to a buffer derotation damping device for satellite docking, and belongs to the technical field of on-orbit repair and maintenance of spacecraft. 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] For satellites whose life is terminated due to control and propulsion system failure or fuel exhaustion, orbital rescue with takeover control and assisted positioning can be used. At...

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 , and does not consider the use of damping mechanism to correct the influence of attitude error
