Experimental study on the effects of higher mechanical dynamic vibration in cross country skiing

Abstract

The mechanism of ski sliding still has not been completed clarified. Previous studies have reported that as the sliding speed increases in alpine skiing, the coefficient of kinetic friction between the ski and the snow surface decreases, and the strength of higher order frequencies generated in the ski increases. However, the cross-country ski has not been studied yet and it is unknown what kind of influence the similar high-order vibration frequency has on the running. In this study, by conducting hammering test by hammering, vibration experiment by simulated vibration generation simulator, 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 basic materials of a sit ski development which is a Paralympic sports game using the cross-country ski.
