Study on Modification of Ski Referring Characteristic of Ski-Turn (Change of Width and Shoe Center)

An approach is proposed for automatically modifying a shape and shoe center (design valuables) of a ski. The proposed approach needs the inverse analysis method (sensitivity analysis) and two indices of the ski turn (“Locus of ski turn” and “Rotational angle of ski”) as the objective functions. Firstly, to obtain the two indices of the ski turn, the outline of the numerical approach for a ski turn is introduced. Subsequently, the sensitivity analysis is shown to estimate the change quantities for the modification of the ski. Finally, referring two indices of the ski turn, a prototype ski is modified into an objective ski by tuning the width and shoe center of the ski. From the above-mentioned numerical calculations, it follows that one can efficiently modify the prototype ski by using the proposed approach.
