Problems solved by technology

The compensation accuracy of passive gravity compensation is low, which has a great impact on the test results; active gravity compensation can improve the compensation accuracy, but the current active gravity compensation method generally provides three degrees of freedom through single-point suspension or six degrees of freedom through multi-point suspension. Motion space, aiming at realizing the goal of spacecraft motion reproduction, the three-degree-of-freedom motion space is obviously not enough, and the six-degree-of-freedom space provided by the multi-point suspension will lead to poor test r

Abstract

The invention discloses a suspension type six-degree-of-freedom micro-gravity environment simulating system. The suspension type six-degree-of-freedom micro-gravity environment simulating system comprises a simulation spacecraft, a space three-dimensional driving follow-up unit, an attitude follow-up and fixing unit, a buffering and sensor mounting unit and a control unit. The space three-dimensional driving follow-up unit follows the position motion of the spacecraft and compensates for the gravity borne by the spacecraft. The attitude follow-up and fixing unit can follow the attitude adjusting motion of the spacecraft and can keep the existing attitude of the spacecraft after the attitude of the spacecraft is adjusted. The buffering and sensor mounting unit comprises a buffering module and a sensor mounting measurement module. By means of the buffering module, the gravity compensation precision is improved for the system based on the property that force on a spring cannot change instantly. The sensor mounting measurement module comprises a wireless tilt angle sensor and a tension sensor, and closed-loop control over the system is achieved. The control unit controls motion of a servo motor according to the measurement results of the sensors, and follows motion of the spacecraft actively.

Description

Technical field [0001] The invention belongs to the technical field of ground verification of space missions such as spacecraft and detectors, and in particular relates to a six-degree-of-freedom microgravity environment for ground verification of space movement of spacecraft. Background technique [0002] At present, the core content of space missions is space cooperation, which mainly refers to various on-orbit services including rendezvous and docking, supply and repair of space stations, and rotation of astronauts. The general steps for the implementation of these space missions include: the determination of the mission content, the design of the implementation plan, the ground test verification of the plan, the development of the mission executor, the on-orbit verification of the plan, and the final implementation of the space mission. Six stages, each stage Indispensable. As a key part of the ground verification of space mission implementation, the goal of the ground ...
