航天员在空间站内的不同舱段间穿行时常常会遇到失定向的问题。为了探究不同穿舱路径对航天员完成定向任务的影响,建立了多舱段的空间站虚拟环境,并开展试验,研究了不同穿舱路径中完成定向任务绩效的差异。结果表明:定向任务的绩效在不同种类的穿舱路径间具有显著差异,失重条件下运动方式的变化会造成定向任务绩效的下降。研究结果可以为航天员空间站内定向训练和空间站内导航辅助标识的设计提供参考。
Astronauts often encounter the problem of losing orientation as they walk through different sections of the space station. In order to explore the impact of different launching paths on the astronauts’ completion of the orienteering task, a multi-segment space station virtual environment was established and experiments were carried out to study the differences in the accomplishment of orienteering tasks in different launching paths. The results show that the performance of the orientation task has significant differences among the different types of threading paths, and the change of the exercise mode under the condition of weightlessness will result in the decrease of the performance of the orientation task. The results of this study can provide reference for the orientation training in astronaut space station and the design of navigation aids in space station.
