Coupled Motion of Snowboard and Elastic Foundation Due to Snowboard Control

Using the numerical approach developed by the authors, one can discuss qualitatively a snowboarding turn. However, the reliability and accuracy of the approach have not always been verified since it is very difficult to compare directly numerical results with experimental results obtained from the snowboarding turn on a snow slope. Then, it is necessary to discuss indirectly or partially various results estimated numerically comparing the experimental ones. Recently, the authors analyzed experimentally and numerically the contact pressure between the snowboard and linear foundation under the action of a dead weight. Although the resolution of the experimental results was not sufficient due to the measuring equipments used, the contact area estimated numerically coincided well with those obtained experimentally. In the present study, a coupled motion of the snowboard and linear foundation caused by the snowboarder\u27s snowboard control is discussed. The snowboard sold in the market place is used. The urethane sheet is used instead of the linear foundation. In the experimental study, 1) forces, bending moments and twisting moments acting to the snowboard from the snowboarder, 2) the displacements of the snowboard, and 3) the distribution of a contact pressure between the snowboard and linear foundation are measured. The displacements of the snowboard are computed and they are compared with experimental ones
