Forced Vibration Analysis of Coupled Motion System Consisting of Snowboader, Snowboard and Elastic Foundation

It is useful for a development and design of a snowboard to make clear the mechanism of a snowboarding. The authors have proposed a simulating approach for a snowboarding turn. Using the simulating approach, it is possible for us to discuss the effects of the snowboarder (physical strength and mass), the snowboard control (technique and kind of snowboarding), the snowboard (shape and mechanical property), and the slope on the snowboarding turn. The reliability and accuracy of the simulating approach are important for a practical use, and they depend on the reliability and accuracy of the numerical approach for the coupled motion of the snowboard and slope. Then, it is necessary to develop the reliable and accurate numerical approach for the coupled motion. In the present study, the coupled motion of the snowboard and slope is investigated for the discussion of the reliability and accuracy of the numerical approach. Since the experimental study is carried out on a shaking table, the forces due to an uneven of the slope as well as the forces due to the snowboard control are considered. The displacements of the snowboard estimated numerically are compared with those measured experimentally
