Analysis of pressure distributions on skis while skiing is of interest to ski researchers in that it yields useful information on ski design parameters such as spring constant, damping, and dimensional shape in a dynamic environment. Obtaining pressure distribution data on skis while skiing is a complex task due to the amount of instrumentation required and mobility of the skier. Research has been performed on analyzing pressure distributions from skiers on a ski deck using infrared thermography. The ski deck offers a platform where the skier is stationary and the deck (carpet) moves under the skier. As the skier skis on the revolving ski deck carpet, thermal patterns are observed behind the skier on the carpet surface. The intensity of these thermal patterns are proportional to the temperature rise on the deck surface and the pressure applied by the ski bottom to the deck surface. Several thermograms were analyzed for different skiing turns ranging from basic wedge turns through advanced linked turns. Transient pressure distributions are presented for various maneuvers. Infrared thermography coupled with revolving ski deck technology has been used to qualitatively depict ski pressure distributions for ski instructors teaching students how to ski. This has resulted in a quicker and safer learning process. The technique can also be used as a quantitative tool for the analysis of newer and safer ski designs.
