The virtual human work task simulation analyzing system for spacecraft repair comprises a virtual reality real-time rendering and movement data acquiring module for simulating relatively complex action of a spaceman in track repair and moving with constraint or support so as to achieve the real human movement postures, a microgravity virtual environment creating module for achieving free state movement without constraint or support or position transfer movement under total body action so as to obtain the virtual human movement postures under a virtual microgravity environment, and an work task simulation analyzing module for quickly creating and pre-analyzing a general virtual scene and space layout to generate various actions for work task operation process as well as performing man-machine efficiency simulation analyzing for virtual human action so as to achieve feedback optimization or feasibility decision making of the virtual human work task planning.

Description

technical field [0001] The invention relates to the field of manufacturing simulation, in particular to a virtual human operation task simulation analysis system and simulation analysis method for spacecraft maintenance. Background technique [0002] Manned space on-orbit operations are one of the key technologies of manned spaceflight engineering, including on-orbit assembly and maintenance of manned spacecraft, space science experiments, release or recovery of space payloads, space rescue, etc. At present, the training and verification of astronauts' on-orbit operation tasks (including extravehicular activities and extravehicular activities) are mainly carried out in semi-autonomous areas such as neutral buoyancy tanks, weightless aircraft, extravehicular activity training simulators, air pressure chambers, detachment test benches, and air cushion platforms. Physical simulation is carried out in large-scale simulation equipment. The limitations of this method lie in the h...

Problems solved by technology

[0006] (1) The virtual reality rendering of the CAD model needs to be imported into the simulation system in a fixed format. The processing process is time-consuming and easy to cause data loss, especially for large models such as spacecraft;

[0007] (2) The virtual human and the model in the virtual reality environment are all pure geometry without physical properties, and cannot construct and generate motion postures in a microgravity environment: Whether it is Delmia or self-developed simulation software, the virtual human posture library And the real action captured from the space position tracking system comes from the normal gravity environment. In the absence of semi-physical simulation hardware, it is impossible to generate the movement posture of the microgravity environment;
