足球运动中不同旋转球的运动轨迹及力学分析

Trajectory and Mechanics Analysis of Different Spinning Balls in Football Game

足球运动过程中运动员使用不同的脚法会对足球产生不同的受力点,不同的受力点产生不同的旋转球与运动轨迹,为此研究足球运动中不同旋转球的运动轨迹及力学分析。根据计算出的速度值轨迹追踪不同旋转状态,非线性变化处理后,设定采样分布距离,得到运动过程中旋转球的坐标,完成对足球运动中不同旋转球的运动轨迹的研究,分析得到小球在旋转运动过程中共受到四项作用力的作用,证明所提方法能够获取足球运动中不同旋转球的运动轨迹并完成受力分析。

In football games,athletes using different skills will produce different stress points on football,and different stress points will produce different spinning balls and trajectories.Therefore,it is necessary to study the trajectory and mechanical analysis of different spinning balls in football games.This paper tracks different spinning states based on the calculated speed value trajectory,and sets the sampling distribution distance after nonlinear transformation to get the coordinates of the spinning balls in the process of the movement.And the author further completes the research on the trajectory of different spinning balls.The result shows that the ball is affected by four forces during spinning process.It is proved that the proposed method can obtain the trajectory of different spinning balls and complete the force analysis in football games.
