摘要
为了研究负重大小和负重位置对士兵行军步态的影响,采用三维运动捕捉测试技术获取士兵负重行走下肢步态,采用足底压力测试系统得到足底步态。试验结果表明:负重大小对士兵的步态有显著的影响,当负重大于20 kg时表现出显著变化。虽然较小质量的负重布置位置对士兵的主观感受未产生影响,但试验结果却表明较小质量的负重改变了士兵行军的步态,其中前后左右均匀布置重物对士兵行军步态影响最小。该研究结果为单兵综合作战系统的负重布局和士兵负重标准的制定提供定量参考。
The effects of load carriage and its location on soldiers＇ gaits during marching are investigated.Walking gait of lower limb is measured by 3D motion analysis system,and the plantar pressure is obtained by plantar pressure measurement system. The measured results show that the gait of soldier is affected by load carriage,especially when the load is heavier than 20 kg. Although light load has no influence on soldiers＇ subjective feeling,the tests in the present paper show that lighter loads change soldier marching gait,in which uniform weight distribution benefits kinematics of gait.
