The purpose of this study is to investigate a viscoelastic model which can generate two dimensional ground reaction force in steady pace running. In previous our studies, we had proposed 3 degrees of freedom viscoelastic model which could generate not only the vertical ground reaction force precisely but also the rebound velocity which is almost same as the rebound velocity in experiment. According to the angle of the ground reaction force calculated from the ratio of vertical and horizontal ground reaction force during contact period, the model should have a rotational control element because the rotational behavior of the model showed a complicated movement. Therefore, the nonlinear rotational elastic and viscous elements were incorporated to the model for governing the rotational behavior. And the parameters of the model were obtained with parameter searching. In conclusions, there were some significant error between the experimental data and the simulation conditions though, the two dimensional ground reaction force was reproduced with the proposed model.
