An Experimental Study on Structural Dynamics of Competitive Alpine Skis between Commercial Products and Custom-made Products for Japanese Top Ski Racers

Abstract

Since carving ski has appeared, the advance of ski gears and operation techniques are remarkable. That is, by angling and deflecting the ski, it is easy to turn with few decelerating elements that draw a narrow trajectory along the deflection curve, so that the ski gears can also be operated and ski techniques has also advanced to make use of the repulsive force of the deflected ski as a driving force. In the alpine competition ski, there is a difference in time due to the difference in the deflection characteristics of the ski. Therefore, by using the experimental method of structural dynamics on the difference of the deflection characteristics between the commercial production skis and the custom-made production skis for Japanese top ski racers.
