Study on Index Optimization of Human-mechanics Based on Basic Ergonomic Evaluation of Spacesuit Gloves.

Objective To search for scientific and applicable human-mechanical optimum indices for basic ergonomic evaluation of spacesuit gloves.Method Thirteen undergraduates(7 male and 6 female)participated in manual performance evaluation studying with barehand and with the simulated spacesuit glove through strength,fatigue,tactile perception,range of motion(ROM) and dexterity 5 studying indices(28 testing indices),and the 28 testing indices were optimized by using statistics and knowledge of anthroposomatology.Result "Grip force" was selected as the optimum strength test index,"subjective fatigue and performance fatigue" as the optimum fatigue test index,"adduction/abduction,flexion/extension and rotation" as ROM test index,"shape perception" as sense-perception test index,and "pegboard and knot tying" as dexterity index.Conclusion The results can provide reference for performance evaluation of spacesuit glove ergonomics.
