Space tether assembly anti-shock buffer release control method and experimental device

Abstract

The invention discloses an impact-proof buffer release control method and experiment apparatus for a space tether system combination body. The impact-proof buffer release control experiment apparatus comprises a master control computer, a visual sense detection device, an optics identifier, an object emulator, an elastic tether, a tether folding and unfolding apparatus, a task platform emulator and a basic platform. An impact-proof buffer release ground experiment platform capable of simulating a space microgravity environment is designed, and a foundation is laid for verifying effectiveness of proposed control strategies on the ground. The impact-proof buffer control method for the tether system combination body is simple, effective and capable of realizing impact-proof buffer control over the combination body via tension force control over tethers so as to prevent system impact and collision The method is advantaged by simple control, rapid control responses, strong robustness, convenience of engineering implementation and the like. The method is suitable for controlling the space tether system combination body on general occasions. The impact-proof buffer release control method and experiment apparatus can be used for simulating the ground experiment platform in a weightless environment in space, and the platform can be widely applicable and can be used for conducting other relevant space simulation experiments.

Description

technical field [0001] The invention relates to the control of the rope assembly after being captured by a space rope net, in particular to a control method and an experimental device for the anti-shock buffer release of the space rope assembly. Background technique [0002] The operation of the space rope net capture system can generally be decomposed into task processes such as rendezvous and approach, rope net launch, target wrapping and locking, dragging off-orbit, and target separation. These processes generally need to be realized through tether retraction and tension control. The target capture process is a relatively complicated process. The mission platform approaches the target through the tracking and aiming system, and the speed difference between the two is controlled within a certain small range before the rope net is launched. Errors, rope net launch, collision between the rope net and the target, rope net wrapping and other links will all produce energy excha...

Problems solved by technology

In addition, the tension of the flexible tether is a passive force. It must have an external force to act on the tether to generate tension, and the magnitude of the tension is also determined by the external force. The direct result of the tension is to deform the tether. At the level of mechanism, its production methods are very different, so it is unrealistic to establish a universal tension model, and it must be analyzed in combination with specific applications
