摘　　要：目的研究人体上肢处于可达域的舒适握力与最大握力。方法根据中国成年人体身高尺寸,按百分比选取510名受试者(男性250名,女性260名),以典型抓握动作为基础,设计30°肩关节伸展、0°、30°、60°、90°、120°、150°、180°肩关节屈曲角度,测量在8个不同肩关节角度的舒适握力及最大握力。结果男性平均舒适握力(30±16)N,女性平均舒适握力(27±15)N。男性平均非优势手最大握力(302±77)N,男性平均优势手最大握力(326±82)N,女性平均非优势手最大握力(198±73)N,女性平均优势手最大握力(214±79)N。男性舒适握力为最大握力的10%左右,女性舒适握力为最大握力的14%左右。身高等因素与舒适握力、最大握力相关系数较大。结论通过研究特定作业姿势的握力数据,可为航天及地面活动使用的产品工效学设计提供参考。Objective To study the comfortable grip force and maximum grip force of human upper limb in reachable domain. Methods According to the distribution of Chinese adults＇ height,510 subjects（ 250 males and 260 females） were selected to participate in the experiment based on typical grip operation. Grip forces from different joint angles including 30° shoulder joint extension,0°,30°,60°,90°,120°,150°,180°shoulder flexion angles were measured. Results The mean and standard deviation of comfortable grip force values（ in N） were 30 ± 16 for males,and 27 ± 15 for males,respectively. The mean and standard deviation of maximum grip force for non-dominant and dominant hands were 302 ± 77 and 326 ± 82 for males,and 198 ±73 and 214 ± 79 for females,respectively. The mean comfortable strength was about 10% of the mean maximum strength for males,and the ratio for female was about 14%. There was evident correlation between volunteers＇ height and the grip force. Conclusion By studying the grip force data of specific working postures,reference may be provided for ergonomic design of products used in space or on the ground.
