粒子要素法を用いた砂上走行における人体下肢と砂粒子のシミュレーション(身体・運動解析)

In this study, we perceived the important leg, in order that people might move. Purpose of our study is to suggest the optimum running method by explaining change of a reaction force and a speed in case of grand differences. We calculated the reaction force and the running speed using the four-link model of the leg. As a result, compared with the case of running on the asphalt and the case of running on the sand, the running speed decreases 15.8% in running on the sand. So we carry out the simulation using Particle Element Method (PEM) in order to restrain decrease of the speed in running on the sand, and suggest the optimum running method.
