Generating two dimensional ground reaction forces with a viscoelastic runner model

The purpose of this study was to propose a viscoelastic model which can generate two dimensional ground reaction forces in steady pace running. In our previous studies, the 3 degrees of freedom viscoelastic model was proposed to reproduce the vertical ground reaction force and rebound velocity. 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 needed the rotational control element because the rotational behavior of the model was a very complicated movement. To generate the two dimensional ground reaction force of running, the nonlinear rotational viscoelastic elements were incorporated to the model and the parameters of the model were calculated with parameter searching. The two dimensional ground reaction force was reproduced with the proposed model.
