通过建立和数值计算跳雪运动员滑翔阶段的运动微分方程 ,模拟了跳雪运动员的滑翔阶段。以我国优秀运动员刘树明和亚布力滑雪场的 K90 m级跳台为模拟条件进行的模拟实验结果表明 ,该方法不仅具有方便快捷的特点 ,而且还能较为详尽的了解速度、受力、迎角等的变化情况 ,这对确定运动员的最佳起跳参数是很有益处的。另外 ,从模拟实验的结果可观察到运动员感受到的“第 2次”飞翔的存在和其产生的原因。
By establishing and numerical calculation of the differential equations of motion during the gliding stage of the jumping skiers, the gliding stage of the jumping skiers is simulated. The results of simulation experiments using the simulation results of the elite athletes Liu Shu-Ming and Yabuli Ski Resort in K90 m stage show that this method not only has the characteristics of convenience and quickness, but also can understand the speed, force, angle of attack Changes, which determine the best athletes take-off parameters is very useful. In addition, the results of the simulation experiment can be observed athletes feel the “second” the existence of flying and its causes.
