摘　　要：高台跳雪是一项广受民众喜爱的极限运动,在雪坡上跳出最远距离是衡量高台跳雪成绩的一项重要指标,然而高台跳雪运动在雪坡上的运动距离受诸多因素的影响,本文对跳雪运动员在雪坡上的起跳角度进行了研究,通过建立物理模型,将高台跳雪运动过程抽象为斜面上的抛体运动,并建立了相应的运动学方程,得出了起跳角度与雪坡上运动距离的函数关系,研究结果可为运动员在高台跳雪运动中跳出最远距离提供理论指导.High platform snow jumping is a popular extreme sport.Jumping the longest distance on a snow slope is an important indicator to measure the performance of high platform snow jumping.However,the distance of high platform snow jumping on the snow slope is affected by many The influence of factors,this paper studies the take-off angle of snow jumpers on the snow slope.By establishing a physical model,the process of high platform snow jumping is abstracted as projectile motion on an inclined plane,and the corresponding kinematic equations are established.The function relationship between the take-off angle and the distance on the snow slope is shown.The research results can provide theoretical guidance for athletes to jump the farthest distance in high platform snow jumping.
