| Research Abstract |
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.
