The slipperiness of ice is well known while, for ice skating, its mechanism still needs further investigation, where the complex interactions including the thermal conduction of the skate—meltwater—ice system, the ploughing and the frictional melting of ice to the friction force are still unclear. This study presents a theoretical framework and a simplified analytical solution to unveil the friction mechanism when a curved skate sliding on ice. The theory is validated by experiments and the effects of these various factors, including the sliding velocity, the ice temperature, the supporting weight, and the geometry of the skate blade to the friction are revealed in detail. This study finds that the contribution of friction force from the ploughing deformation through skate indentation and that from the fluid friction through the shear motion of the meltwater layer is comparable with each other, which thus clarifies how the ploughing deformation of the ice substrate together with its frictional melting regulates the friction during skating.

犁耕和摩擦融化如何调节滑冰摩擦

冰的滑性是众所周知的,但对于滑冰来说,其机制仍需进一步研究,其中包括冰鞋-融水-冰系统的热传导、冰的犁耕和摩擦融化与摩擦力等复杂的相互作用。仍不清楚。这项研究提出了一个理论框架和一个简化的分析解决方案,以揭示弧形溜冰鞋在冰上滑动时的摩擦机制。该理论经过实验验证,并详细揭示了滑动速度、冰温、支撑重量和冰刀几何形状等各种因素对摩擦力的影响。
