目的为支持航天任务中航天员作业能力变化规律方面的研究,建立航天员空间操作人因分析一体化仿真平台。方法分析了该平台的系统结构,给出了控制流程及软件各部分的详细实现方法,包括认知和生物力学仿真,作业可视化,负荷预测与绩效分析等软件。结果通过手控交会对接任务作为用例,对平台功能进行了实验验证,实验结果证实了平台的可行性、有效性和实用性。结论平台的认知和生物力学模型可实现人在回路外的仿真,可对负荷与绩效进行预测及可视化显示,为进一步分析航天员在太空操作能力的变化奠定了技术基础。
Aim To support the research on the changing rules of astronauts’ operational capability in space missions, an all-in-one artificial simulation platform for astronaut space operations was established. Methods The system structure of the platform is analyzed. The control flow and the detailed implementation of each part of the software are given, including softwares of cognitive and biomechanical simulation, job visualization, load forecasting and performance analysis. Results The hand-held rendezvous and docking mission was used as a case study to validate the platform functions. The experimental results confirmed the feasibility, validity and practicability of the platform. Conclusion The cognitive and biomechanical models of the platform can simulate people outside the loop, predict and visualize the load and performance, and lay the technical foundation for further analysis of the astronaut’s operational capability in space.
