Coupled motion of ski and elastic foundation under ski control

The authors have proposed a simulation approach for estimating a ski turn and have numerically obtained various useful results on the ski turn using the simulation approach. A coupled motion between the ski and snow slope is caused by a skier's ski control during the ski turn. In the simulation approach the coupled motion must be analyzed. In the present study, a numerical approach to the coupled motion is justified by comparing the numerical results with the experimental ones. In the first experiment, the ski's motion due to an impact force is measured in order to consider the repeatability of the experiment and the justification of the numerical approach. In the second and last experiments, the ski's motion due to the skier's ski control is considered in order to justify the numerical approach to the coupled motion. Furthermore, the edging force applied to the ski by the skier during the ski control is measured.
