車いすマラソンのシミュレーションモデル構築

抄録

In order to improve the performance in wheelchair racing, it is important for players to use the optimum wheelchair and to propel it in the optimum manner. However, only trial and error is conducted in the present training situation to find them. In order to consider the whole dynamics of player and wheelchair, a simulation model was developed in the present study. In this model, forces were given on joints of upper body, as well as between hand and handrim. Also, the forces between tyres and road were calculated by the magic formula. As a result, the experimental situation was successfully reproduced in this model, and the torque acting on joints were investigated. The developed model enabled to evaluate wheelchair and propelling style.
