Ergonomics implications of extravehicular activity spacesuit glove

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.
