航天员舱外维修操作时间的量化评估
Quantitative assessment of extravehicular maintenance operation time for astronauts
摘要
Abstract
For space stations to operate safely in the space environment,astronauts'extravehicular maintenance tasks are essential.Therefore,it is essential to quantitatively assess the time required for these operations to ensure the success of extravehicular activities and the safety of astronauts.In this study,we present a quantitative technique for evaluating astronaut operational time during extravehicular maintenance activities,with the goal of designing and analyzing the duration of astronaut extravehicular operations to fulfill extravehicular time requirements.The proposed method takes into consideration the influence of the microgravity environment and the reference motion time of the joint in the literature data,which was modified by the modular arrangement of predetermined time standard(MOD)method,and the uncertainty range of the reference motion time of the joint was obtained by fitting the literature data with the least square method.For the working conditions of different astronauts and different extravehicular tasks,a comparative analysis with publicly available videos of extravehicular activities was conducted to verify the accuracy of the assessment method and provide a feasible basis for the time required for astronauts'extravehicular maintenance operations.关键词
