Mathematical Modelling of Biomechanical Interactions between Backpack and Bearer during Load Carriage
Figure 8
The simulated relative pack displacement along the back (mean (solid red line) one standard deviation (dashed red lines), (a)), compared with measured data (mean (solid blue line) one standard deviation (dashed blue lines), (a)), for six repeated trials for one subject (age: 28 yrs, weight: 71.8 kg, height: 178 cm), and measured vertical trunk CoM displacement (mean (solid blue line) one standard deviation (dashed blue lines), (b)). The average walking speed was m/s, and the pack load was 11.5 kg. The stance phase for the left limb is from 0 to 59%, and the swing phase is from 59% to 100%. The double support phase is from 0 to 9% and from 50 to 59%.
