摘要
基于有限元方法,建立网球和球拍击球过程中的冲击分析模型。模拟不同入射角、球速、旋转等因素对球拍反作用力的影响。结果显示:入射角大的球产生的反作用力比入射角小的球大;相同速度不同入射角的旋转球所产生的反作用力均大于平击球;相同球性网球入射角大的球产生的反作用力均大于入射角小的球。
The study uses the finite element method (FEM) to establish the impact analysis model in the process of tennis playing, trying to probe into the influence of different incident angles, speed and spin on the reaction impact force of the racket. The findings show that there is a larger reaction impact when the player plays from a bigger incident angle. In addition, the spin ball has a greater impact than the fiat ball when the ball is played with the same incident velocity in different incident angles. Finally, there is a greater impact for a ball from a big incident angle with the same sphericity than from a small angle.
