负重对足迹质量的影响

The Effects of Weight-bearing on the Quality of Footprints

从100组立体足迹捺印样本中抽取10组进行数据统计和形态分析,分别以背负、抱负、单手体侧提、双手体前提的姿态负重15公斤进行捺印取样,并测量其步幅特征及步态特征;再分别以背负、抱负、单手体侧提、双手体前提的姿态负重5公斤-20公斤进行捺印取样并测量其步幅特征及步态特征。通过对以上数据的分析、总结,发现负荷重量的变化及负重的方式的改变会对足迹的步幅特征和步态特征产生不同的影响。在实验中发现这种变化,还受到个体力量差异、行走习惯等因素的影响。

This article counts and analyzes 10 pairs of three-dimensional footprints from 100 collected samples respectively, samples them from differern situations： bear, vision, put one hand side, the premise of hands posture and body weight 15KG, and measures the characteristics of their stride length and gait features; then samples footprints of carrying vision, single-hand side mentioned, the premise of hands posture and body weight 5-20KG and studies them. Through the above analysis of the data, we sum up that changes in load and load change in the way of the footprints on stride characteristics of gait characteristics and produce different effects. Experiment found that this change also affected by individual differences in strength, walking habits and other factors.
