Clarification of Tribology Characteristics between Snow and MechanicalMaterials under Low Temperature and High Velocity Conditions

为了设计和开发更有效和高效的除雪机械，必须澄清低温和高剪切速度条件下雪与机械材料之间以及雪中的摩擦学特性。我们设计并开发了一套环形剪切型实验分析系统，可以测量雪与机械材料之间以及在这些条件下雪中的剪切特性。利用该试验分析系统，分析了雪与机械材料之间以及雪本身的摩擦学特性，特别是雪与机械材料之间的摩擦特性和粘着/内聚力特性。研究了摩擦系数和单位面积粘着力/内聚力随雪型和剪切速度的变化规律。

To design and develop more effective and efficient snow removal machines, clarification of the tribology characteristics between snow and mechanical materials and in snow is necessary under low temperature and high shearing velocity conditions. We originally designed and developed an annular shearing type experimental analysis system that can measure shearing characteristics between snow and mechanical materials and in snow under those conditions. The tribology characteristics, especially the characteristics of friction and adhesion/cohesion between snow and mechanical materials, as well as in snow itself, were analyzed by using this experimental analysis system. The variations of friction coefficient and adhesion/cohesion force per unit area with the snow type and the shearing velocity were clarified and discussed.
