| Outline of Final Research Achievements |
To elucidate mechanism of skiing friction and deformation properties by indentation of snow surface have been experimentally investigated at Shinjo cryospheric environment laboratory, Sugadaira space radio observatory, and so on. By using a tribo-meter influence of snow temperature and sliding velocity on coefficient of friction has been clarified. In case of polyethylene the coefficient became larger in two regions, that is, high temperature and low velocity, or low temperature and high velocity. And also the coefficient didn’t change so much in high velocity. By hardness test using conical or flat indenter influence of density, temperature, and grain size of snow on hardness has been clarified. Thereby, edging profile and shape of compaction area under the indentation in skiing can be predicted.
