摘要：The mechanism of ski driving still has not been completed clarified. Previous studies have reported that as the driving speed increases in alpine skiing, the coefficient of the kinetic friction between the ski sliding surface and the snow surface decreases, and the strength of higher order frequencies generated in the ski board increases. However, the mechanism of the cross-country ski driving has not been studied yet and it is unknown what kind of influence the similar high-order vibration frequency has on the driving. In this study, by conducting hammering test by the Impulse hammer, vibration experiment by the simulated vibration generation simulator system, analysis of frequency strength of board, characteristics of cross-country ski such as relationship between sliding speed and coefficient of kinetic friction were clarified. Furthermore, it was aimed to obtain the fundamental view point of a sit ski development which is a Paralympic sports game using the cross-country ski.
