用摩擦磨损试验机法测定了10 cm长的模型滑雪板在低速（0.005~ 1 m/s）下的摩擦系数。系数值取决于滑动速度、雪温度和雪粒度。在任何温度下均未观察到负载效应。静摩擦系数与接触时间的对数有关。对于较小颗粒的雪，随着温度的升高，系数增大。实验结果表明，模型滑雪板低速摩擦力的来源是雪与聚乙烯之间的剪切力。
Frictional coefficients of a model ski (10 cm length) were measured at low velocity (0.005~ 1 m/s) by means of the tribometer method. The coefficient values depend on sliding velocity, snow temperature and snow grain size. No load effect was observed for any temperature. The static frictional coefficient was depended on the logarithm of the contact time. Further, the coefficient increased with the temperature going up for the smaller grain snow. These experimental results show that the origin of the friction force of the model ski at low velocity is the shearing force of the adhesion between snow and polyethylene.
