舱外航天服手套的工效问题

Ergonomics implications of extravehicular activity spacesuit glove

为提高舱外航天服手套的工效,分析了影响其工效的主要因素:手指皮肤温度低于1 5 .6℃会使工效明显下降,压力总是对手套工效有显著的影响,形状结构使手套工效存在±5 0 %的差别,好的材料能改善手套关节点的特性.提出解决手套工效的关键在于处理好手套的形状和结构.从舱外航天服手套的设计、制作和增加辅助装置等几个方面探讨了提高工效的方法.并从力量、疲劳、灵活性、触觉、活动范围和舒适性六个方面介绍了评价手套工效的方法.

For enhancing the work efficiency of extravehicular activity (EVA) spacesuit glove, the main factors of affecting spacesuit gloves on performance were analyzed. The performance would decline quickly if the temperature of finger skin is under 15.6°C, the pressure always have significantly affects the manual performance, glove structure and figuration makes efficiency have ±50% difference, and good material can make glove joint more flexibility. The key to solve the work efficiency of the spacesuit glove was considered as the configuration and geometry size of the spacesuit glove. The means to improve EVA performance were discussed base on spacesuit glove design and manufacture and assisted devices. The methods of evaluating glove performance were introduced from strength, fatigue, dexterity, tactility, ranger of motion and comfort.
