This study constructed finite element models of the foot and soccer ball, and examined the factors affecting the ball behavior in curve kick. The models were validated by comparing the results of the finite element analysis to those of the experiment. Simulations of the ball behavior were conducted using the finite element models. The simulation results indicated the following. The ball velocity is largely affected by the foot velocity immediately before impact but barely affected by the Young's modulus of the shoe upper and the coefficient of friction. The ball rotation is affected by the foot velocity immediately before impact and the coefficient of friction; however, these factors had no significant effect.

本研究建立了足部和足球的有限元模型，考察了曲线踢中影响球行为的因素。通过将有限元分析结果与实验结果进行比较，验证了模型的正确性。利用有限元模型对球的性能进行了模拟。仿真结果表明：球的速度在很大程度上受撞击前的脚速度的影响，而几乎不受鞋面的杨氏模量和摩擦系数的影响。球的旋转受撞击前的足部速度和摩擦系数的影响；但这些因素均无显著影响。
