Description

One of the authors proposed a numerical approach for analyzing bending deformation and vertical displacement of a ski, vertical deformation of snow, and reacting force acting on the ski from the snow when vertical force and bending moment act on the shoe center of the ski lying on the snow. In the present study, the justification of the approach has been discussed by comparing numerical results with experimental ones. Since it is very difficult to measure the vertical displacement of the ski lying on the snow, the displacement of the ski lying on a urethan sheet was measured when only the vertical force acted on the shoe center of the ski or when vertical force and bending moment acted synchronously on the shoe center of the ski. Furthermore, it is concluded that the correction of camber height is necessary for the numerical analysis of dynamic bending deformation of the ski lying on soft snow.
