面向出舱活动中航天员肌肉状态和体力负荷的风险评估,为了实现航天员肌肉激活的预测,开展了着常服和舱外服两种工况下不同操作位置的推、拉、提、压共8组典型功能操作实验,测试航天员最大施力能力的同时采集了肱二头肌长头、肱三头肌外侧头和三角肌前束的肌电信号. 提出基于人-舱外服耦合运动生物力学模型预测着舱外服人体的肌肉激活,并预测了两种工况下8组典型功能操作的肌肉激活. 通过预测结果和积分肌电值的相关性分析,验证了模型预测的有效性,为研究人-舱外服真实交互方式提供了新的方法学思路,对肌肉激活的预测为出舱活动任务规划提供了生理学依据.

This paper aims to predict the muscle activation of astronauts in EVA for ergonomic as-sessment of their physical states. Typical functional tasks such as pull, push, press and lift in vari-ous places were conducted by 9 participants in both spacesuit-unsuited and suited conditions to col-lect maximum force and sEMG ( surface electromyography) of RT Biceps BR. , LT LAT. Triceps and RT ANT. Deltoid. Muscle activations in these functional tasks were predicted based on the pro-posed framework of human-spacesuit integrated biomechanical modeling. Model predictions were val-idated through the Pearson correlation analysis between predicted muscle activations and measured sEMG. The proposed human-spacesuit integrated biomechanical modeling offers a new insight into human-spacesuit interaction and physiological bases for EVA planning.
