130 Fabrication of simulated vibration source simulator in ski driving

Abstract

The purpose of this study is to develop the simulated vibration source simulator in ski driving based on the new concept which is able to reproduce more than 200Hz machine dynamics vibration affecting velocity in skiing in order to clarify the ski driving mechanism. The simulator used snow mass simulating skier, and it glided over the bottom surface of ski. In experiment, compressor and ball vibrator used as a way of source of vibration, these were able to reproduce the similar vibration in skiing. The experiment was carried out using this simulator. From is experiment, the snow mass velocity was increasing in accordance with increasing of the vibration frequency, and the coefficient of dynamic friction were between 0.018 and 0.035 in snow mass gliding.
