| Outline of Final Research Achievements |
To design and develop more effective and efficient snow removal machines, clarification of friction and cohesion/adhesion characteristics between snow and mechanical materials and in snow is necessary in high shearing velocity under high pressure and low temperature 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 to the system that can shoot and observe a high speed and micro phenomenon such as generating and a flow of water between snow and mechanical materials and in snow with high definition. We created an environmental system for conducting experiment analysis under the controlled low temperature condition. The characteristics of friction and adhesion/cohesion between snow and mechanical materials, as well as in snow itself, were analyzed by using these experimental analysis systems.
