Experimental Research on Layout Accessibility of Individual Load-Carrying Equipment

摘要

Using three-dimensional motion capture and surface myoelectricity system, this study showed the characteristics of upper limb's movement and surface electromyography in the process of picking and placing the Soldier System's module on load-carrying equipment. The study aims to evaluate the accessibility to nine representative layout locations of load-carrying equipment. It can make an important contribution to the layout and optimization of individual load-carrying equipment. The results of this investigation showed that: (1) The maximum change of the upper arm's angular velocity and integrated electromyography of muscles biceps brachii both can evaluate accessibility, yet the former had more significant and representative than the latter. (2) There was a significant positive correlation between the accessibility of soldier's carriers in front part of the body and the movement distance of hand. Soldier System's modules which are high frequently accessed were appropriate for the more accessible position.
