| Research Abstract |
The purposes of this study are to develop a simulator generating a ski board vibration in actual skiing and to perform the basic construction for clarifying the ski sliding mechanism. In simulators, the surface on the bottom of the ski was assumed as to be a snowy slope and a snow pack assuming a skier had slid on this ski bottom surface. The vibration on the ski was caused by a ball vibrator. A dynamic friction force, a coefficient of kinetic friction and the velocity of the snow pack were measured and calculated when the snow pack was sliding. The experiment was carried out in the low temperature laboratory. The velocity of the snow pack with 250 Hz vibration was higher than that without vibration. The coefficient of kinetic friction with vibration was lower than that without vibration. Furthermore, as increase in velocity of snow pack, the coefficient of kinetic friction was decreased. From these results, the simulator is suitable for clarifying the ski sliding mechanism.
