An Integrated Simulation Platform for Human Factors Analysis of Astronaut Space Operations

Abstract：Objective To study the changes of astronauts' operation capacity in long-term space missions,an integrated simulation platform for human factors analysis of astronaut space operations was established.Methods The architecture of the integrated simulation platform was analyzed,and the implementation of each part of the control flow and software platform were given,including management and scheduling subsystem,cognitive process simulation,biomechanical simulation,multiple integrated model communication,task execution process visualization,cognitive workload prediction and performance analysis.Results Taking a rendezvous and docking mission as a case study,the functions of the simulation platform were verified by the experiment,and the experimental results demonstrated that the simulation platform established in this paper was feasible,effective and practical.Conclusion The cognitive system model and biomechanical simulation model provided in the platform can realize the human out of the loop simulation,and can be used in the prediction and visualization of cognitive and biomechanical workloads and performance analysis for a specific space task,which will pave the way for the further analysis of astronauts' operation capacity in space flight.
