Abstract

The temperature rise distribution in a snow ski track yields information on the performance of the ski. High temperature rise indicated high pressure such as an edged ski while low temperature rise indicated less pressure such as a gliding ski. Preliminary research is performed on snow ski tracks using infrared thermography. Several thermograms are presented showing the temperature rise in ski tracks on a motorized ski deck and on a ski slope. Temperature rise (about 7C) was easily acquired on the motorized ski deck because of the high coefficient of friction between the ski and the ski deck nylon carpeting. Temperature rise on the ski slope was much lower (about .3C) and much more random because of snow surface variations. Preliminary results indicate that infrared thermography can be developed into a useful tool by the snow ski designer.
