Tool spacecraft system for on-orbit control

Abstract

According to the tool spacecraft system oriented to on-orbit control, docking mechanisms are installed on the upper portion and the lower portion of a spacecraft base of the system, a plurality of rigid mechanical arms and a plurality of flexible mechanical arms are installed on the spacecraft base, and end effectors are installed at the tail ends of the flexible mechanical arms and the tail ends of the rigid mechanical arms. The technical problems that a space robot only has a rigid mechanical arm and does not have a flexible mechanical arm, the space robot cannot adapt to narrow space and complex structure operation, the number of the mechanical arms is small, only one or two mechanical arms are arranged, the executable task is single, the function is limited, and a tail end operation mechanism carried by a traditional space robot is single and cannot give consideration to multiple tasks are solved. The tool spacecraft system is provided with four rigid mechanical arms with 7 degrees of freedom and two flexible arms with 12 degrees of freedom, and the six mechanical arms are arranged, so that the diversity of operable tasks of the spacecraft system is greatly improved, the function of the spacecraft system is expanded, and the reliability of executing the tasks of the spacecraft system is improved.

Description

technical field [0001] The invention relates to a tool spacecraft system for on-orbit manipulation, in particular to an on-orbit manipulation spacecraft system with multiple mechanical arms, and belongs to the technical field of spacecraft on-orbit services. Background technique [0002] In recent years, human spaceflight has developed rapidly, and the number of satellite launches has been increasing year by year, but every year, a certain number of satellites fail to successfully enter orbit or fail. According to statistics, satellites that fail to enter orbit correctly and fail after entering orbit account for about 10% of the annual launch volume, causing huge losses to the development of the aerospace industry, and in-orbit services can solve most of its problems. In order to occupy the space application and technology level in advance, countries are competing to develop on-orbit service technology, which has become a new commanding height in the scientific and technolog...

Problems solved by technology

[0005] In order to solve the problem that the space robot mentioned in the above background technology has only rigid manipulators and no flexible manipulators, it cannot adapt to narrow spaces and complex structures. The number of manipulators is small, and there are only one or two manipulators, which can perform a single task. , the function is limited, and the terminal operating mechanism carried by the traditional space robot is single, unable to take into account the technical problems of multiple tasks, a tool spacecraft system for on-orbit manipulation is proposed
