Abstract

The invention relates to a spacecraft on-orbit maintenance ground virtual verification system. The spacecraft on-orbit maintenance ground virtual verification system comprises a human-machine interaction system, a virtual scene system, an external display system and a maintenance evaluation system, and the human-machine interaction system is used for displaying the virtual on-orbit maintenance process for a spaceman in trial and completing virtual on-orbit operations through data gloves with force feedback; the virtual scene system is used for simulating the on-orbit maintenance scene and process of a spacecraft; the external displaying system is used for displaying the virtual on-orbit maintenance process and maintenance data; the maintenance evaluation system is used for evaluating the on-orbit maintenance effect according to the virtual on-orbit maintenance process and the maintenance data displayed by the external displaying system and modifying the maintenance scheme according tothe evaluation result. The invention further relates to a spacecraft on-orbit maintenance ground virtual verification method implemented through the system.

Description

technical field [0001] The invention relates to a virtual verification system and method for the on-orbit maintenance of a spacecraft on the ground. Background technique [0002] Objects in space are in a weightless state, and astronauts’ actions in space are difficult to control. Many maintenance methods that are considered reasonable on the ground may not work in space. To ensure the success of on-orbit maintenance, ground verification and training trials of on-orbit maintenance must be carried out on the ground. [0003] At present, the widely used on-orbit maintenance ground verification method is to conduct neutral buoyancy simulation test on the ground. For example, ground-based simulations of Hubble's in-orbit repairs are carried out in the neutral buoyancy simulator at the Marshall Space Flight Center. A full-scale model of the Hubble telescope, equipment to be replaced and maintenance tools are placed in the simulator, and the astronauts wear diving pressure suits...
