Abstract
Although it is difficult to turn a sledge well for a rider who rides in it, general beginners will be able to ride in the sledge which is different from a pair of skis requiring a great deal of technical skill in their operations. In this study, a snow sledge that is possible to turn freely was proposed. At first, we applied the principle of Alpine ski robot to sliding of the sledge, and suggested a simple form as a snow sledge made of GFRP. Moreover, the base shape of the sledge was decided according to the experiments with 1/6 plastics models of the sledge. As a result, we made it clear that the relations between the edge shapes of the base and the movements of the center of gravity. Finally, we proposed a snow sledge made of GFRP, and carried out the real sliding test.
