| 摘 要： | 本文通过计算和分析宽度不变和侧面切削两种不同形状的滑雪板的受力以及相对重心的力矩,得出了侧边切削的滑雪板更容易转动的结论;通过解滑雪板运动的微分方程,发现滑雪板的削边对其曲线运动轨迹的半径有极大的影响。

| Abstract: | Modelling the turning motion of snow skis is simulated via a single-ski rep-resentation followed by numerically solving the associated differential equations of motion, The forces applied to the ski are assumed to be gravity. The longitudinal friction occurred be-tween the ski and snow and a skidding force (snow resistance force) corresponding to a sys-tem centripetal force and making curvilinear motion possible. The skidding force is calculated via a water jet analogy. Our model quantitatively shows that a ski's side-cut remarkably af-feets the radius of curvature of a ski trail made when skiingdown a ski slope. |
