Embodiment Construction

[0025] specific implementation plan

[0026] The specific content and working process of a method for eliminating the rotation of complex moving bodies under microgravity by bionic adhesion and verification device of the patent of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] The racemization method uses a bionic adhesive structure to change the traditional purely mechanical capture and locking method, without matching interfaces and target cooperation, and only needs to select a suitable surface of the target spacecraft to achieve capture and reliable connection. With a new design concept, an innovative mechanism can be formed, which can simplify the system design and operation process, reduce control requirements, reduce device quality, reduce costs, and comprehensively improve my country's target acquisition and connection capabilities.

Abstract

The invention discloses a biomimetic adhesive microgravity complex movement body rotation elimination method and a verification device, and belongs to the technical field of air on-orbit services. The method is mainly characterized in that a flexible force bearing pulling part with an adhesive material is used for making adhesive contact with a rotation elimination target at first, then firm adhesion is formed, and finally a flexible force bearing band applies external force to the rotation elimination target to achieve rotation elimination. The verification device comprises a system support (1), a large inertia rotary body system mounted on the system support, a first pulley system, a second pulley system and a flexible adhesive rope (6). According to the rotation elimination method, a biomimetic adhesive structure is used for changing a traditional pure mechanical acquisition locking mode, interface matching and target cooperation are not needed, and acquisition and reliable connection can be achieved just by selecting proper surfaces of a target space vehicle. An innovative mechanism is formed through the brand-new design philosophy, the system design and operation processes can be simplified, the control requirement is lowered, the mass of the device is lowered, the cost is lowered, and the target acquisition and connection capacities of China are improved comprehensively.

Description

technical field [0001] The invention discloses a method and a verification device for eliminating the rotation of complex moving bodies under bionic adhesion under microgravity, which can be used for the derotation work of space debris, invalid satellites and other space rotating bodies. The disclosed verification device is used for simulating the derotation principle The verification and testing of equipment belong to the field of aerospace on-orbit service technology. Background technique [0002] The cleaning or recycling of satellite debris requires the technical capability of reliable acquisition and connection of out-of-control, non-cooperative, and non-matching interface targets. At present, space manipulators are mainly used for on-orbit services, such as the SRMS system in Canada, the ETS-VII system in Japan, and the SLES system in Europe. Through the cooperation of robotic arms and astronauts, the United States has successfully realized the maintenance of the Hubb...
