Free vibrations of a snowboard

Toshiyuki Sakata; Shigehiro Kawai; Fumio Kawada

Because of the rapid increase in the number of snowboarders many kinds of snowboards have been developed recently. To design a snowboard or to improve its quality, the natural frequency of the snowboard seems to be one of the most important properties to be discussed. In this study whether or not one can accurately estimate the natural frequency of the snowboard by using the numerical approach proposed for a free vibration of an inhomogeneous plate is discussed. First, the convergency of the natural frequency is discussed from the numerical results. Next, this study investigates whether or not the natural frequency is accurate enough for practical usage by comparing the natural frequencies obtained numerically with those obtained experimentally. Finally, the effect of snow on the natural frequencies is discussed.
