通过对雪面反作用力的测量，对单板滑雪雕刻转弯进行了运动分析。雪面反力测量系统安装在滑雪板和滑雪板之间，该系统可以利用多个三轴紧凑力传感器的输出来测量雪面的六维力分量(力和力矩)。我们进行了由高技能单板滑雪运动员进行的雕刻转数的测量实验。结果表明，雪面反作用力从秒到秒的变化规律。此外，我们还将本研究的结果与前人的研究结果进行了比较，并计算了滑雪板的扭矩和挠度，以表示影响滑雪板转弯的重要因素。结果表明，由于滑雪板运动员技术的不同和滑雪板的偏转力矩的不同，滑雪板在减重和转弯调整时产生的反力也不同。这一结果可用于阐明单板滑雪转弯的机理，评价单板滑雪运动员的技术水平。
This paper deals with the motion analysis of carving turns in snowboarding by the measurement of reaction force from snow surface. The measurement system of reaction force from snow surface is installed between the snowboard and bindings, and the system can measure the 6-axis force components from snow surface (force and moment) using the outputs of several 3-axis compact force sensors. We conducted the measurement experiment of carving turns performed by a high skill snowboarder. The results showed how the reaction force from snow surface varied from sec to sec. Furthermore, we compared the results of this study and the previous study and we calculated the moments of torsion and deflection of snowboard for denoting the important factors in carving turns. The results showed the differences of reaction forces according to the difference of the snowboarder’s skill and the deflection moment of the snowboard for the unweighting and the adjustment of turn. The results can be used to clarify the mechanism of snowboard turns and to evaluate the snowboarder’s skill.
