摘　　要：为了研究航天员穿戴舱外活动(EVA)手套时活动范围的变化规律,在低压模拟舱中使用不同的手套充压条件,用摄像头提取了4种工况下12个手部关节设定动作的图像,通过标志点确定了特定关节角度,并测量了角度的数值,最后对数据进行了方差分析。结果表明:随着压力增大,压力对活动范围的影响越发显著;戴有压手套对掌指关节弯曲活动范围影响不大,而对近端指间关节和手腕的活动范围影响却很显著。压力对手套不同区域抑制作用并不完全一致,在未来的EVA手套工效学设计中,应更多地考虑除掌指关节之外其他关节的活动性。To study the variations of the range of motion of astronauts when wearing gloves(EVA),different glove charging conditions were applied in the low pressure cabin and a camera was used to extract images of 12 hand joint settings in 4 conditions.The angle of the specific joint was determined through the marker points and the angle values were measured.In the end,the data was analyzed by ANOVA.The results showed that as the pressure increased,the effect of pressure on the range of motion(ROM)became more significant.Wearing a pressure glove had little influence on the ROM of knuckle flexion,but significant influence on the ROM of the proximal interphalangeal joint and wrist.The inhibition effect of pressure on the glove were different in different regions.In the ergonomic design of the future EVA gloves,more consideration should be given to the mobility of joints other than the metacarpophalangeal joint.
