A Study on Development and Application of Simulating Approach for Ski Turn

通过2000 - 2001年的研究，得到了以下结果：1.我国的经济发展状况。边沿运动（滑雪控制）数据库的制作：在实验室或雪坡上对各种滑雪控制进行录像。录像中的滑雪控制是“下-上-下”运动、“曲线滑雪”和“平行转弯滑雪”。从录像图像中建立了滑雪控制的数据库。滑雪者模型的设计和滑雪者控制模型的制作：用多体系统对滑雪者进行建模。使用滑雪板模型产生了许多滑雪者的姿势，并通过将滑雪者的姿势按顺序排列成连续的图片来产生滑雪控制。获得的结果将发表在日本滑雪科学学会杂志上，并在2002年7月在日本举行的2002年第一届亚洲多体动力学会议上发表演讲。滑雪板形状和机械性能数据库的制作：测量了许多滑雪板的形状和机械性能。根据实测数据建立数据库。滑雪板与基础的耦合运动研究：对滑雪板在弹性基础上的运动进行了实验和数值分析，实验结果证明了滑雪板耦合运动的数值计算方法是正确的。该研究于2001年7月在瑞士举行的“ISB国际生物力学学会第18届会议”上发表。滑雪设计方法的发展：一种新的滑雪设计方法。在2001年9月于加拿大举行的“国际工程多学科设计会议CSMIE-MIDE 2001”上提出。进一步改进的方法计划在2002年7月在奥地利举行的“国际机电一体化会议MECH2K2”和2002年9月在日本举行的“第四届国际体育工程会议”上发表。这些陈述已被采纳。滑雪机器人的实验研究：一次滑雪的实验表明，为了将模拟方法应用于雪坡上的滑雪，还必须对模拟方法进行一些改进。少

By the research during 2000 to 2001, the following results have been obtained:1.Production of the database for edging motion (ski control): In the laboratory or a snow slope various kinds of ski control were videotaped. The ski controls videotaped were "Down-unweighting---Up-weighting" motion, "A curved line skiing", and "Parallel turn skiing". From the videotaped pictures the database of the ski control was made.2.Design of skier's model and production of ski control model : A skier was modeled by a multibody system. Using the ski model many skier's postures were produced and the ski controls were produced by putting the skier's postures in order as a continuing pictures. The results obtained are scheduled to contribute to The Journal Japan Society of Ski Sciences and to speak at The First Asian Conference on Multibody Dynamics 2002 being held in Japan on July of 2002.3.Production of the database for shape and mechanical properties of skis : The shape and mechanical properties of many … More skis were measured. From the measured data the database was made.4.The study on the coupled motion between ski and foundation : The motion of the ski resting on the elastic foundation was discussed experimentally and numerically The numerical approach for the coupled motion was justified by the experimental results. The study was presented in the "XVIIIth Conference of the ISB International Society of Biomechanics" held in Switzerland on July of 2001.5.Development of designing approach for ski : A new designing approach for. ski was proposed at "International Conference on Multidisciplinary Design in Engineering CSMIE-MIDE 2001" held in Canada at September of 2001. Further improved approaches are scheduled to present at "International Conference on Mechatronics MECH2K2" being held in Austria on July of 2002 and "The 4th International Conference on The Engineering of Sport" being held in Japan on September of 2002. These presentations have been already accepted.6.Experimental study using skiing robot : The experiments for a skiing made clear that we must improve a little the simulating approach for the application to the skiing on the snow slope.
