摘　　要：目的建立实用的手动作业的疲劳评价方法,为舱外航天服手套的作业疲劳评价提供可行分方法。方法对12名女性和14名男性分两组进行了握力、捏力和拧力的疲劳固定力量和无因次力量疲劳的实验研究。结果从握力、捏力和拧力进行研究可全面评价手部疲劳;无因次力疲劳评价有较广泛的适用范围和较好的准确度,与主观疲劳评价相结合是最佳方法。结论本文结果可为有效地评价舱外航天服手套系统作业疲劳提供可行的方法,具有一定的实际意义和应用价值。Objective To find a biomechanical evaluation methods of manual performance fatigue, for providing the feasible methods for the hand fatigue of spacesuit glove, Method Twelve females and forteen males in two groups served as the subjects and participated in the experiments of changeless force fatigue, including gripping, pinching and screwing, and took part in the nondimensional force fatigue. Result Manual performance fatigue could be fully evaluated based on gripping, pinching and screwing. The nondimensional force fatigue had widely applied ranges and well veracity. The combination of nondimensional subjective and objective evaluations was the optimal fatigue evaluation method. Conclusion The results can provide the feasible methods for performance evaluation of spacesuit glove system.
